  2. Hello,


    You can now get verified on forum.

    The way it's gonna work is that you can send me a PM with a verification picture. The picture has to contain you and forum name on piece of paper or on your body and your username or my username instead of the website name, if you prefer that.

    I need to be able to recognize you in that picture. You need to have some pictures of your self in your gallery so I can compare that picture.

    Please note that verification is completely optional and it won't give you any extra features or access. You will have a check mark (as I have now, if you want to look) and verification will only mean that you are who you say you are.

    You may not use a fake pictures for verification. If you try to verify your account with a fake picture or someone else picture, or just spam me with fake pictures, you will get Banned!

    The pictures that you will send me for verification won't be public


    Best regards,

    StanleyOG.

    Hang on a second. Zero is a number in the real world as much as any other number can claim to be. Granted it's debatable if any number really exists outside of mathematics, I would say they all do (apart from maybe complex numbers), but many Philosophers would disagree. However, zero meets all the same standards as any other number which you would claim to be a number of the real world. The numbers you are referring are called Natural numbers in mathematics, it's generally accepted these days that zero belongs in the set, there are still a couple of number theorists that don't believe zero belongs, as it makes some things awkward, but that's no excuse.

    The original brain-teaser was either trivial or impossible depending on how one interprets the rules. As for the Building Houses puzzle, that's a rather difficult problem. I was just interested in seeing how many points people could manage. The maximum number achievable is far from infinity. It's actually 17.

    This problem was first solved as late as 1970.

    The easiest way to calculate this is actually by multiplying. You start with 2 and multiply by 3 then 2, 5, 7, 2, 3, 11, 13, 2, 17. Split the sum into fractions and find out which numbers exist in each area.

    I own a number of houses. That number is zero.

    Bullcrap. I do NOT own a number of houses. I do not own houses, period.

    If 0 isn't a number then that means that 1-1 must equal -1 as it would be the next number below 1.

    What you have there is a failure of the English language to incorporate zero. Many other languages around the world do not have this problem.

    I found two bugs. Your equation makes for NaN (not a number) and the PHP syntax highlighting was probably meant for a white background, it looks bloopy on blue.

    However, if I use greater than or equal to operators for the even and odds, I do get one answer.

    No
    If you have one and one is taken away . you have nothing . zip . zero.
    1-1= (no number) 0

    You can't actually have -1 of anything.
    however.
    if you loose 1 or 1 is taken away you can be minus one.

    I would have posted a javascript instead of a PHP, but you couldn't test it because modern browsers don't let you paste into the web consoles without turning off a security preference (self-xss). Plus, this forum only has syntax highlighting for PHP.

    LOL , that's debatable , but I couldn't care less and it's not a debate I will waste any time on.
    Numbers are nothing but a means of enumerating how many of things , measurements on scales and so on , so what/which adjective you use is really of no importance in every day life.
    Interestingly , when numbering how many of things , only zero always means same .
    When one person has a hundred elephants and another has a hundred knuclebones , they each have something entirely different , but , when they both loose all and the first has no elephants and the second has no knucklebones , then they both have the exactly the same , nothing , zero.
    Now that's interesting . They have nothing , and since there is nothing to count when you have none , how can zero be a number , since it designates that there is nothing to count.
    mmm , food for thaught ,
    but I still don't care what you call it , because nothing changes what it means.

    ha ha , yep :rolleyes:
    but it has posed some interesting questions around numers/numerics and language and nomenclature , while filling time. :joyful:

    Interesting? or absolute tosh ?

    A direction/bearing of zero degrees is still a direction. A bank balance of zero doesn't mean no bank balance. A temperature of zero doesn't mean without temperature. Zero G is a valid measurement that doesn't mean nothing (G force can be positive or negative). When systems are in equilibrium, they are described with the value zero. I could go on for ages.

    Oh dear , I think you should reread what I said.
    You see , like maths , the English language is generally quite specific.
    See the word things , as in "when numbering how many things"
    I have mentioned other examples of numbering also [like scales , temperatures etc.] elswhere , and since they are so obvious , see no point in rehashing . They have nothing to do with what I was talking about , and like you , I could go on , and on , and on , for ages . but I have no interest or intention to do so.
    since this:
    Wee Hector said:
    If 0 isn't a number then that means that 1-1 must equal -1 as it would be the next number below 1.
    and I replied;
    No
    If you have one and one is taken away . you have nothing . zip . zero.
    1-1= (no number) 0

    You can't actually have -1 of anythin
    :end quote.
    is where this nonsense started , it is exactly where I am leaving it. :thumbsup: bye

    WeeHector is just misunderstanding the point. Whereas you are just simply wrong. You can absolutely have -1 of something. You could have -$1 sitting in your bank account, in which case you have a debt. A debt is a situation where you would have to obtain money, just to return to a point where you have zero money. There is no complication here. Zero is a number. When it is not assigned to a scale it has a null value, but it does not mean it is not a number.
