back to article Camelot pulls scratchcard amid numerical anarchy

Camelot has withdrawn its short-lived "Cool Cash" scratchcard after it required a higher than absolute zero grasp of how numbers work to understand it. According to the Manchester Evening News, to qualify for a prize, punters had to "scratch away a window to reveal a temperature lower than the figure displayed on each card". …

    Yay math

    "I phoned Camelot and they fobbed me off with some story that -6 is higher, not lower, than -8, but I'm not having it."

    Goodness this girl is thick, maybe someone should have explained it in math she would understand.

    If you borrow £6 off your mum till your giro arrives, and your sister borrows £8 to feed their 15 sprogs till their giro arrives, who owes the most to your mum?

    I may be getting confused with the confusion. Camelot say you have to find a lower number than say -8. And the woman thinks that -6 is a lower number, even a lower temperature. Is she thick? -10 surely would be the lower number. Surely Camelot should have told her to stuff it.

    People who do not have a basic grasp of mathematics should not be allowed money of there own, and they certainly shouldn't be allowed to purchase anything that requires them spending it and, shock, horror, incur the possibility of having to subtract £1 from the £5 they have used to purchase said scratch card.

    *Shakes head in disbelief*

    "On one of my cards it said I had to find temperatures lower than -8. The numbers I uncovered were -6 and -7 so I thought I had won...- the card doesn't say to look for a colder or warmer temperature, it says to look for a higher or lower number."

    "The Manchester Evening News concludes: "More than 15 million adults in Britain have poor numeracy - the equivalent of a G or below at GCSE maths." "

    Tina Farrel said, "On one of my cards it said I had to find temperatures lower than -8. The numbers I uncovered were -6 and -7", and later, "the card doesn't say to look for a colder or warmer temperature"

    So, which is it Tima? Did it say you had to find lower temperatures, or did it not? You contradict yourself.

    She also said, "it says to look for a higher or lower number. Six is a lower number than 8. Imagine how many people have been misled."

    But, the numbers were -8 and -6, not 8 and 6, -6 is definitely a higher number than -8, so even on the "numbers not temperatures" idea, you're wrong.

    Camelot are in the right here - it's our schools who should be ashamed of themselves.

    Uninformed comment follows:

    OK, so I've not seen one of these scratch cards but, going by what the young lady interviewed said, she has a point. If the card says to look for a lower number, then 6 is lower than 8.

    There are even situations where people who "do have GCSE" mathematics may consider numbers absolute -- for instance, surely a line at -110V is at a higher voltage (albeit negative) than one at -10V? Then again, I've forgotten most of my education, so that may not be the case.

    Now I'm confused.

    They are also, supposedly, temperatures. Perhaps she might have a case if they haven't specified which temperature scale each number uses.

    "surely a line at -110V is at a higher voltage (albeit negative) than one at -10V?"

    No. In order to be + or - there must be a reference of zero, and relative to that reference -110V is a lower voltage than -10V.

    Whether either of them is a *more dangerous* voltage depends entirely on where you are. If you're sitting on a metal plate at -110V then touching a wire at -110V won't be a problem, but touching one at -10V (or +10V for that matter) would be most unpleasant, to say the least. High doesn't inherently mean dangerous, it just means, well, high. When I stepped out of bed this morning I realized that I was 900m up above sea level.

    @anonymous coward: "money of there own" is one hell of a mistake to make when complaining about other people being stoopid!

    @Cameron Colley: The numbers in question are "-8" and "-6", not "8" and "6". If I were to ask you which was higher of "92" and "87" would you say '7' since it's higher than '2'???? With respect to the voltage question - when people are asked about the "highest voltage", that's often interpretted as "furthest from ground" (not saying this is right, just that it's how it is read). If you were to ask which was the higher potential you'd get the correct mathematical number.

    It's really depressing that this is something people get wrong, and it's more of a comment on the skills that people are taking into the world as adults than anything else.

    Camelot (for once) have my sympathy.

  24. Jack Garnham

    @Cameron Colley

    Uninformed indeed, you have completely missed the better part of the discussion here. 6 is lower than 8, correct. -6 (negative six) is higher than -8 (negative eight) though!

    On your second point, I am hardly qualified to comment but I was under the impression that a voltage must be relative. i.e. a Voltage is a measurement of difference. In your example you would be correct in saying that -110V is a higher voltage than -10V provided that the opposite terminal is 0V (or any other voltage higher than -10V). Giving a Difference or Voltage of 110V and 10V respectively. So you're correct here, although I'm not sure you're aware of it. If the opposite terminals were +100V and 0V respectively then they would both measure the same Voltage of -10V overall.

    Feel free to correct me if I'm wrong, someone.

    Negative Feedback

    @Cameron Colley: You're right that 6 is a lower number than 8, but those aren't the numbers that are causing the problems. Those numbers are -6 and -8, and -8 /is/ lower than -6 ... the minus signs aren't just punctuation to make it look tidier, they're part of the numbers themselves, and make them distinct from 6 and 8!

    As far as voltages go, if you're dealing with DC and wanted to know if a wire was safe you might just call -110 a figuratively "high" voltage - in that case you'd be using shorthand for "high magnitude". If you were comparing one voltage to another for any functional purpose you'd definitely take sign into account when deciding if one was higher than another. If you're working with AC, which is far more likely to be the case for high voltages, you'll be comparing peak or RMS values which are always positive in any event.

    If a number is positive, then it is greater than a negative number, therefore:

    3 > 2 > 1 > 0 > -1 > -2 > -3 etc...

    And for those of you who failed primary school maths, the little arrow means that thenumber on the left is greater (has a higher value) than the number on right. Please also realise that a number is never "minus one" as this means "subtract one from the previous number" - it is always "negative one".

    Lol, you do realise that you suggesting that -110 V is higher than -10 V "albeit negative" is the kind of logic that gets kids failing their GCSEs. No, -10V, is, and always will be, higher than -110V. Volts are a relative unit, just like temperature in degrees, and so you can adjust the reference as you like, so comparing -110V and -10V is EXACTLY the same as comparing 0V and 120V, the latter is the higher in both cases.

    So, perhaps in Tina's defence, possibly techies too have issues with basic maths..........

    Voltage is potential *difference* and is therefore inherently absolute, when you say "-110V", the potential difference is 110V, the minus sign is just extra information about what direction the electrons are flowing in the circut, really.

  60. Edward Rose

    @Cameron Colley

    The sign on a voltage only dictates the direction the current will flow. Other than that, it's pretty meaningless. Given the voltage is the amount of energy per unit charge then the values should be assumed as absolute when comparing for which is 'higher'.

    So -110V is, to all intents and purposes, higher than -10V. It's the same as 110V and 10V, it just pushes the current off in a different direction.

    110V and -110V have exactly the same energy per unit charge. So your analogy is slightly off point.

    Camelot should be forced to pay a heavy tax to the government. That way, the working class may get a chance of getting their money back off the scrounging class.

  61. Anonymous Coward

    Uninformed comment follows: (Probably just as uninformed as the original.)

    I know exactly what you mean. Voltage is often referred to as "PD" or the Potential Difference between two points, where as the positive or negative refers to the direction in which the charge potentially travels. If you were measuring with a volt meter and reverse the connections you would get a reading on a -110V as +110V.

    So in this case, I would say that you are right. No doubt someone who is wholly a lot more verse in electrics that I am may well shoot me down in flames.

    But one thing for sure is, a -110V shock would hurt more than a -10V one.

    Just to confirm

    We were definitely expected to understand negative numbers in primary school (this is mid-90s). I distinctly remember getting a sequence question which went something like 5, 4, 3, 2. I was one of the few who wrote "1, 0, -1, -2". Most of my classmates wrote "1, 0, 6, 7" or something equally awesome. That would have been around 8 or 9 years of age.

    Funny the things you remember from childhood - I wasn't particularly conceited about getting that right or anything. I think I remember it because of the complete failure of most of my friends to even understand the concept of negative numbers - even the thickest kids know what addition is even if they can't actually do it.

    So to answer the question, you do learn negative numbers in primary school, but most people are too stupid to understand them.

    @ Cameron Colley

    When people talk about "high voltage" they generally refer to the RMS or absolute magnitude, as you could also ask a similar question about AC versus DC here.

    It comes down to scalar with magnitude only, (e.g. reference to "240V system") versus vector with some form of orientation in 1 or more dimensions (e.g. -110V as more negative than -11V, so lower in the conventional orientation of sign & magnitude).

    voltages when talked about as voltages in the real world, ie power lines, are relative to mother earth, so -110v is the greater voltage, higher was a bad term, but it is also the term that would be used in the field.

    OTOH, if working inside equipment, it could vary depending on what the designer wanted to use as a ref: point.

    Greater<>higher and double negatives do not necessarily cancel.

    If you grab hold of a wire at -10V and then another at -110V I think you will be left in no doubt as to which is greater.

    And whether it is regarded as higher or lower surely depends on the context which is not the case with temperature.

    The jargon definitions of greater than and less than in mathematics and computer programming are not identical with the meaning of the same strings of symbols in conversational English (and anyway in both mathematics and computing unambiguous symbols are used not the aforementioned words).

    If one wishes to speak unambiguously about temperature then surely the words hotter and colder should be used not higher and lower nor greater than and less than.

    Double negatives have a long and honourable history as intensifiers. As far as I can tell they fell into disrepute when attacked by the same idiots who tried to forbid split infinitives.

    This whole affair reminds me of culturally dependent IQ tests.

    Sorry - however much you'd like to believe that there is a hard and fast rule that states that saying 'minus' only means subtract, language isn't always as prescriptive as you'd like.

    If you check a dictionary, you'll find that using the word 'minus' is perfectly acceptable to indicate a negative numerical value. (In fact it's actually called a 'minus' sign, so reading -4 aloud as 'minus 4' would be appropriate just for that reason)

    Hang on people....

    Look, negative numbers are a purely theoretical concept, as is zero.

    Our brains haven't evolved to cope with quantities that imply non-existance, because quite plainly we have never been exposed to stimuli that don't exist.

    Heck, when they first tried to introduce these systems in Europe they were so mind-bogglingly bizarre that it is claimed peolpe were burned at the stake for using them!

    The majority of us here see negative numbers as second nature because we've been drilled with extended cartesian geometry (I believe Descartes himself started at zero and counted up) and modulo arithmetic in polar geometry.

    In polar terms, by convention we see all angles in terms of clockwise rotation, and have to treat anti-clockwise rotation as a negative rotation. Have you ever told anyone to turn "negative right"? No, you say "left".

    Negative numbers are not natural, and while it's a sad state of affairs that schools are failing to teach the concept adequately, it's not necessarily an indicator of individual stupidity.

    The negative number story is a bit sad. But for readers of a technical forum the number of respondents who clearly would fail basic physics is almost as bad.

    Voltage is and always has been a relative measure. You must include the sign. Try putting the batteries into your latest toy backwards. Yes, loose use of the measure abounds, but usually in a context where the missing qualifier is implicitly understood. So in power delivery it is understood to be AC. (However if you were to be correct in a power system you would take notice of the phase, and would also understand that the relative nature of the measure remains critical - and just why the neutral is tied to ground.)

    The voltage on the anode of a CRT is thousands of volts, and is positive with respect to the cathode. But where they sit relative to the chassis ground is another matter. Either end could (in principle) turn you into a raisin.

    My point, as is slightly borne out by the comments above, is that talking about higher and lower and using negative numbers can be a little confusing, in this particular case only to a complete muppet, but if you stretch the situation a little even those who are relatively educated may see some confusion (I'm sure if I had time I could say something about vectors and magnitude).

    When you're talking about gambling, it pays to be _very_ explicit, and I can't help thinking that someone at Camelot realised this would happen and that was why negative numbers were used.

    Volts and mags

    Funny how this evolved from temps and normal number scaling to electric current discussion.

    Voltage is "potential differential", and for practical purposes we usually use the absolute value, the sign indicating the polarity of such current in DC. AC is always positive. So,

    -110V == (110, -) V (say, v1)

    -10V == (10, -) V (say, v2)

    So, |v1| > |v2|

    Voltage is potential difference - a measure of electric potential energy. -110V is a greater PD than -10V, thus a 'higher' potential difference too.

    Building site electrical supplies run at a total potential difference of 240V in the UK, like our domestic circuits. Power tools and so on work fine down at the site or at home. However unlike house electrics which have the live side at 240V and the neutral at 0V, they run at -110V and +110V. This is done to give Tina's brother a fighting chance when he severs one of the cables with his spade.

    @Alex McMahon

    Your example doesn't quite work as your initial statement is that the "2 people start running away from each other". Therefore the directional element of each velocity is expected to be the exact opposite of the other.

    Suggesting that the one running moves with a negative velocity would put him on the same directional heading as the other, just with a greater magnitude. The faster runner will be running away from the slower but the two are not running away from each other.

    The speed is just the magnitude of the velocity thus 20m/s is obviously faster then 10m/s given the fixed starting frame of reference.

    the -110V question is wrong. The -110V terminal if it

    is CD is lower. Which way will the (positive) current flow? Toward you. If it's +110V, it will flow out of you. Current flows to the lower potential.

    If it's AC, then the -110V is still called the 110V line and occasionally becomes 0V, so the question in this case is moot.

    (note for the pendants out there: i.e you should be hung :-), electrons flow the opposite way to current but that is why they have negative charge. The voltage differences were defined before they knew what was causing the current)

    But another way to explain to the poor woman what's going on is to ask "what makes one number lower than another?" to which you could say "you can keep subtracting one from the higher number to get to the lower one". So taking away something makes it less. Lower is an aptonym (I think). So when you take one away from -8 (making it a slightly lower number) what do you get? -7? No. -9. Will you ever get to -6 this way? No. Now try it on the -6. Oh, -7, -8. So which is the lower number? -8.

    forget about you with the 110V. Think about the current. Which way does current flow? From HIGHER to LOWER potential. Rather like which way does the river flow: from HIGHER elevation to LOWER.

    Which way does the current flow from you waggling about to the -110V potential? From GROUND to YOU to CIRCUIT. So is -110V higher or lower than GROUND/YOU? Lower.

    Does your body like current flowing from your hands to your feet but NOT from you feet to your hands? No. It doesn't like either. Why? Because you don't care where the current is going, your body doesn't like being a resistor.

    Now, lets say you're standing on a diode that only allows current to flow from you to the ground. Now touch the -110V potential. Anything? No. Now touch the 10V one. Oooh. Tingly. Now touch +110V. OWowowowowowow! So is 110V higher than -110V? Yes. Is 10V higher than -10V? Yes. Is 110V higher than +10V? Yes. So given these three statements, we should be able to work out the answer to the question "is -110V less than -10V". And the answer is...

    Lotteries, and other forms of state-run gambling, are not simply a tax on people who are bad at math. They are also a voluntary tax. So the more people who choose to pay it, the lower my mandatory taxes should be (at least theoretically). As long as they don't bring in crime and use up extra resources, I'm all for it.

    I live in Maryland, USA. We have a long and storied history of horse racing here. The Preakness, middle jewel of the (American) Triple Crown, is run here. All the surrounding states have installed slot machines at their tracks. The state legislature wants to put them in here too, to bring back all the people who have defected to Delaware, W. Virginia, and Pennsylvania, and resuce the failing racing industry by fattening purses with slots revenue (and balance the budget, too).

    One of the tracks is about a mile from my house. I just pray the earmark some of the money to extend the Metro there so the little old blue-haired ladies can keep off my street on their way to pay their voluntary taxes.

    Of course lottery officials on this side of the pond would be smart enough to realize how stupid their clients are, and never would have instituted such a confusing scratch-off card in the first place.

    "At £-10,000 you have a higher debt. But you have lower credit."

    So if I gave you more money, ie INCREASED your money supply, would your debt be

    a) Higher

    b) Lower

    b. isn't it.

    But what is your debt? £10,000.

    So using "higher debt" isn't edifying what "-£10,000" means, does it.

    And, since I've increased your money (your wealth is higher) yet your debt has gone down, what does that show? Debt is negative money. So REALLY what you mean is that you have -£10,000 and are in debt. So adding money (to get a higher wealth) to the tune of, say £1,000 would leave you with -£9,000 which, while STILL in debt, is a HIGHER value than -£10,000. So -9000 > -10000.

    Oh, it went and proved you wrong.

    Alternatively, if you increase your debt by -3,000 and you were in debt by 2,000, you should be on 1,000 credit. But 2,000>1,000 so how did I increase debt and get a smaller number?!?!?!!?

    Not sure if all 'mark' explanations are the same person's, but since we are all being incredibly pedantic the explanation regarding -110V and commenting on 'Stratman et al' has the logical flaw that although you can show -110V as being less than 10V according to the tingle you will also show it as being equivalent to -10V, because in both cases the diode will prevent current passing, so no tingle.

    As far as I can see it all depends upon your definitions - if you define -110V as lower than -10V then it is, if you define -110V as being higher (or greater or larger) than -10V it is. It all depends on whether you are talking about the number or the physical situation the number represents, what your frame of reference is, and of course your PRECISE definition for the terms 'lower', 'higher', 'greater', 'smaller', etc. Because we speak in English rather than a precisely constructed logically framed and defined language it gets a little woolly - hence the apparently intelligent group here getting all hot under the collar correcting one another.

    It isn't a maths question, a physics question or even an electrical engineering question - it's philosophy - and based on the comments we don't have many philosophers here. First step for a philosophical debate - define your terms of reference. Unambiguously. Exclude all other definitions. A dictionary is not sufficient.

    Well, what matters except where current flows in electricity? If no current flows, it doesn't matter what voltage is. Nowt happens.

    Saying that you get as much zap from -110V as +110V so they are the same is to say that the himalayas are the same height as the sea because if you're facing upstream you'll drown just as well as if you faced downstream.

    So current flows from higher to lower voltage. a 6v and 1v potential will see current go from the 6v to 1v terminal. and 6 IS "higher" than 1, isn't it? So if you have 6v rail and a -12v rail, does current flow from the higher -12V terminal to the lower 6V?

    As to using how ochie it is as the definition, you can build up thousands of volts in static electricity and get a bit of a snip. Whack your fingers across the thousands of volts at a local powerstation will see you black and crispy. Same volts.

    Don't knock Camelot's profits, any money left over from any game goes to the charity fund NOT to Camelot.The same applies to unclaimed Lottery prizes

    Camelot take 1/2penny to cover everything! the Government take 12pence for doing what?

    I'm sure they'll come up with a game especially for the hard of understanding soon!!

    Who's stupid?

    Tina's "error" reveals a lack of education (or perhaps a mind that has not succumbed to the straight-jacket that education sometimes is) - but certainly not stupidity. Maths (like language) is a system of conventions. If you're not familiar with the conventions your reasoning is not stupid (-8 being "more small" than -6 becomes ambiguous). I am a mathematician, and whilst I can see what Camelot intended I also know that the ability to think about numbers in unconventional ways is how most of the great advances in my field have been made.

    I'm not saying Tina is a mathematical genius - simply that her "quirk" is profoundly human - and a large part of the reason why there are no "computer" mathematicians, only human ones.

    The arrogance of many of the comments does not reflect well on "techies". If we didn't have people like Tina, we wouldn't have people like Albert Einstein (who was notoriously bad at arithmetic).

    Unfortunately IQ is a normalised scale with the mean centred on 100. So assuming you are of above average intelligence, as you kill off all the populace with the lower IQs, you will bring yourself closer to the mean of the IQ distribution at a redfined 100, and mark yourself for execution...

    Under your scheme pretty soon only Carol Vorderman and Stephen Hawking will be left.

    The future of the planet will be welsh and in a wheelchair.

    Maths lesson

    Surely they shouldn't withdraw these cards - then the people who are confused by them will learn something when they find out (to their chagrin, no doubt) that they didn't win. Much akin to shock therapy (let's face it, it works with rats...)

    Yes the story is funny and worrying at the same time.

    However all I can think about is the stupid sod that has seen this article, has been put straight and is feverishly going through their bins looking for their winning scratch card as they first thought that -10 was higher than -8.

    More Nitpicking

    It is perfectly possible to define the absolute electric potential of a point (The energy required to bring a positive unit test charge of zero mass from infinity to the point). However it is far more common to use some local reference such as the earth and work with potential differences. It's the same with gravitational potential. On a side note gravitational potential is always negative.

    When working with potential differences, the sign tells you nothing about flow of current. The current could be flowing in either direction or even zero. Also strictly speaking a potential difference is defined between two points, whereas a current is defined through a surface. This is often glossed over by talking about the "voltage across" and the "current through" a two terminal component.

    Don't be so negative

    Right, I am pretty well educated and would not have made the mistake that Tina did. However, I never know whether I am turning my fridge up or down so I leave the contol somewhere in the middle.

    PS I am pretty sure that sayiong Negative 1 instead of Minus 1 is an Americanism, I was taught to say minus 1 when we learned about negativew numbers at age 8.

  145. Mark

    And yet more nitpicking

    True, but the idea was "which is higher, -110V or -10V?" There's a potential difference there, but "which is higher" is the -10V because of the direction current will flow.

    As to Tina being merely miseducated, taking the numbers AS NUMBERS will show which one is higher because by SUBTRACTING from one number, you make it less. So if you have a negative 6 and subtract one from it, it gets CLOSER to negative 8. Showing that -8 is lower than -6.

    If you're going to say that negative numbers are difficult because you never see "-6 apples" so it's a merely theoretical construct, then for such people there is no difference between -6 and -8 since you still have no apples whichever number of apples you have. So -6 is not higher than -8. So she still lost.

    Since the cards were winter themed and regarding temperatures, I would find this story even more ludicrous were we to find out there was a cartoon-ish thermometer complete with temperature marks (dipping below zero) printed on the cards...seems like the classic kind of cheese that gets printed on these things.

    Has anybody seen one?

    "That policy has obviously worked a treat then..."

    Well she's 23 and the current government has been in power for ten years, so she'd have been 13 and already started GCSEs by then so hardly a fair criticism.

    I wasn't aware that a G grade had been introduced, but I know that there's now an A*, so just how low do you have to score to fail it entirely? And is -8 a higher or lower mark than -6? :)

    Top story?

    Over 160 comments? Blimey! This story has obviously touched a nerve.

    The fact that most of the people who pour money into Camelot lack any understanding of number is hardly surprising - anyone with basic numeracy skills would take one look at odds of 14,000,000 to 1 against and save themselves a quid.

    As to us IT people, we only need to count from zero to one.

    You are so right to say: "What they really needed was a simple card that revealed "YOU HAVE WON" (or, more likely, "YOU HAVE NOT WON.""

    In my youth i worked in my uncle's newsagent and sold these cards to customers. Its perceived as a 'game' and i often stood behind the till selecting and handing a card over, watching some poor sod examine his scratched card to see if they had won. it struck me then and stuck with me that the whole 'game' was a scam. we all know it, but by obfuscating the 'you win' or 'you lose' message in a simple (?) problem (match 3 icons etc) they made it feel like something else. i wondered how differently people might feel if they just handed me £1 and i just told them 'sorry not this time' but every so often they won and i handed them some cash?

  152. Matt Horrocks

    Shop just as bad...

    "so I thought I had won, and so did the woman in the shop. But when she scanned the card the machine said I hadn't."

    Surprised the woman in the shop wasn't stupid enough to hand over the prize anyway and think "the machine must be wrong".

    My god.

    I've just glanced through some of these comments. People are actually explaining why -6 is higher than -8!!!


    If a number is positive, then it is greater than a negative number, therefore:

    3 > 2 > 1 > 0 > -1 > -2 > -3 etc...


    Jesus christ, even the Digg crowd wouldn't need an explanation.

    @ Niall Tracey... and why voltage isn't like temperature.

    'Have you ever told anyone to turn "negative right"? No, you say "left".'

    Haven't you ever seen the Beatles film "Yellow Submarine"? Right at the end, when the Blue Meanie army is being routed, their leader tries to send them back into battle with the words

    "You're advancing the wrong way! Retreat backwards!"

    And the #1. reason why voltages and temperatures aren't commensurate in this discussion? You don't root-mean-square a temperature, that's why.

  157. Daniel B.

    Still fun...

    Everything came about because of voltage. Oh well...

    I just remembered back in secondary school when I failed a math exam. Funny thing was that one of the problems I got "wrong" according to the teacher was something like this:

    3. Monday at noon, a thermometer shows that we are at 11 ºC. By midnight, however, the temp has dropped down to -3 ºC. Whats the difference between these two temperature readings?

    Guess what: I answered 14. And according to my teacher, I WAS WRONG. And you know what was the most funny thing about this? More than half of the entire class had also answered 8, confirming my fears that I was surrounded by stupid people. Thank God I transferred to another school (and city) 3 months later.
