    well, depending on which way you want the results to be, negative or positive, its not actually different, well, reads these might give you more info. http://www.mathsisfun.com/positive-negative-integers.html http://www.themathpage.com/alg/signed-numbers.htm but to me, there is no different in add or subtract those :) the only different we have is the results it give us :)

    This is a bad question. Subtracting is not an operation Really we are adding the additive inverse of a number, so now we are adding the additive inverse of an additive inverse. \(a-(-b)=a+(-(-b))\). The one on the left is just an abuse in notation.

    I should be very clear and say that subtraction is not an operation on the real numbers as a field because subtraction is not associative. But that was boring. . .
