how do u add integers

Question

anonymous · Answer

I'm not really sure how you want this question answered. An integer is a number that doesn't have a fractional component. So like -1, 0, 1. You add them like anything else.

idk like the question says explain how to add integers

solomonzelman · Answer

idk how to explain but know how to do it.... it's one of those things that you can't really explain so much.

solomonzelman · Answer

6+(-4)
(-10)+(-12)
33+76

like this

anonymous · Answer

Yeah, there's not really a way to explain it, more of examples of how to do it.

addition is a binary operation
when a,b are positive
a+b means $[\underset{a-times}{1+1+1+1+...+1}]+[\underset{b-times}{1+1+1+1+...+1}$]

if either a or b is negative, we have that we add a multiples of the additive inverse of 1, which is -1

suppose a<0, b>0

$a+b=b+a=\underset{b-times}{[1+1+...+]}+\underset{a-times}{[-1+(-1)+(-1)+...+(-1)]}$

similarly if a<0 and b<0.

zzr0ck3r, this is just an elementary question a person doesn't know the basics, and you have no mercy on the keyboard..

zzr0ck3r · Answer

a binary operation that takes two elements in one set, and maps them to another element in the same set. For it to be a binary operation, it must always be defined for two elements. i.e. defined everywhere. So like multiplication is NOT a operation on the real numbers, because $2*0^{-1}$ is not defined. But multiplication IS a operation on the reals without 0.

@SolomonZelman how can we get more elementary than 1+1+1+1+...+1?

zzr0ck3r · Answer

its not so elementary to explain the obvious, which is what this question is asking them to do. hence why every other answer is not an answer to the question, but an example. I made it about as easy as it can be.

p.s. I have been asked this question in graduate level math classes. so don't assume:)
