Generally speaking, the names of variables are irrelevant to what you are actually doing with them.

Can someone just tell me what the variable for subtract is ? thats all i want

Frankly I don't think anyone understands what exactly you are asking.

I took a guess and am telling you that there is no variable name that has to be used with addition nor subtraction. You can call variables whatever you want.

I can say

int sum = 5 / 2;

and Objective-C (or any other language) would be perfectly happy with that.

If you are just interested in the mathematical term for the result of a subtraction for trivia's sake, that would be difference.

It's actually "-", believe it or not.

reading you question literally, I think you mean what variable must you place the difference. "difference" is the word mathamaticians use to decribe the result of a subtraction.

But for coding.

sum = 1 + 2
thing = 1 + 2
var1 = 1+ 2

dif = 3 - 1
thing = 3 - 1
(even)
sum = 3 -1

will all accomplish just what they look like they will accomplish

sum = 9 -1
sum = sum - 5

results in, sum containing 3

You get to choose what the variable name is.
