Integers are positive + and negative -.
We need them because we might want to find a sum or the answer

Negative + negative =positive sign
positive + negative   = depends which number is bigger then you take the sign of it
Negative - Negative = which number is bigger take the sign
Positive - Negative = positive

Now divide and multiply
Negative * Negative = Positive
Negative * Positive = Negative
Negative divide negative = Positive
Positive divide Negative = Negative
