As in multiplying and dividing negative and positive integers?
Well, when you multiply or divide two positive integers, the product or quotient is always positive
If you multiply or divide one negative and one positive integer, the product or quotient will be negative
If you multiply or divide two negative integers, the outcome will be positive because they basically cancel each other out
Also, if you multiply or divide two negatives and then multiply or divide it by one more negative, the answer will be negative because you first had a positive, but then multiplied it by a negative which would become a negative

This is from an old problem that i answered, on how to multiply and divide negatives
Now here's how to add and subtract:
Adding Negatives
negative + negative = positive
negative + positive = negative
positive + negative = negative
Subtracting Negatives
negative - negative = this depends on the order of the negatives, because for example if it's : (-2) - (-3) = 1 or (-3) - (-2) = -1
negative - positive = negative
positive - negative = positive
