    Whats your favorite, the one and all it has to offer, this topic is far more vast and in depth than a cheap poll, give me your thoughts.


    the more science you know, the less crap you get.

    I would say I am a multiplication and addition kind of guy.

    Division often ends up with something messy left over and subtraction is like asdding backwards :?

    Cheers ... :-D

    it's all the same, really. Division is multiplication, and subtraction is addition. Multiplication is also just an algorithmic form of addition. It's all, really, the same thing.

    Arcane Mathematician is essentially correct, but the human mind percieves these operations in a rather different format in addition to the fact that the equivalent operations of division and multipication and subtraction and addition are simplified versions of one another. That's why many people can add and multiply much faster in their head than subtract or divide. Actually, when I subtract, I simply take the second term of the binomials that are conducting the operations, turn it into a negative number, and add the first term of the binomial to it. For example, in the expression 7 - 10, I transform it into the equivalent expression (-10) + 7 to make the arithmetic more fluent mentally.

    No Joshua, I'm right. Multiplication is the addition of equivalent sets of numbers. 3x4=4+4+4=3+3+3+3. It can be repeated any number of times you'd like, to whatever effect you like. That is EXACTLY what it is.



    If that concept is too much for you, I'm sorry, but that doesn't make me wrong.

    subtraction is addition of a negative number,
    multiplication is multiple addition, maybe call it multiaddition!!
    division is mutliple subtraction! multisubtraction!!

    Surely all of maths is just a sequence of additions (if you include negative numbers)!!

    If you can add up you are a maths genius!!

    No. Subtraction does not come from addition and multipication does not come from division. Addition can very well be the subtraction of a negative number when the numbers conducting the operations are positive, or multipication as the division of a number bewteen zero and one when considering postive real numbers. Even than, subtraction, addition, division, and multipication can all be linked. For example, if you have a number x, than the following holds true (where x does not equal zero):



    Another example would include this property:

    While you do seem to understand the operations rather well, the only problem I have with your definitions is that they're rather circular.

    Josh, don't make such positive statements when you have no idea what you are talking about. Being vulgar does not make you correct, it only makes you appear idiotic.

    The operations of arithmetiic, all of them, are derived from some very simple axioms. Those axioms do nothing more than postulate the existence of the natural numbers (i.e. the set {1,2,3,4,5,6,...}). The key to the natural numbers is the existence of a "successor" to each natural number, which is nothing more than simply adding 1.

    So, all of the operations that are used in ordinary mathematics come from nothing more than adding 1.

    If you would like to see this done in detail you might read Landau's book Foundations of Analysis.

    Ultimately this leads to all of the operations that occur with the real and complex numbers and also their completeness which leads to the ability to do exponentiation, differentiation, i
    ntegration --- the whole works.

    Well I suppose saying subtraction is the addition of a negative number is a bit of
    a cheat.

    Not at all. It is in fact the definition of subtraction.

    Poster number 11, insults will not be tolerated at any time, this site is starting to get a little out of control, I know some people have left, and maybe it's time for me and some more to go to, if people don't start acting scientific, where going to have some problems, and no they are not the same thing regardless of what anyone says.

    Poster 11 ? Are you having trouble counting ?

    You in fact initiated the insults with your post (apparently now deleted in false indignation) to Arcane mathematician. See quote in my earlier post that preserves your rudeness.

    Discussion here is actually generally pretty objective, but you created the exception.

    So, if you feel it is time to leave, then don't let the door smack you on your way out.

    Tata.
