Hi! Hope this helps
(- stands for negative and + stands for positive)
Adding
- plus + = - or + depending on the numbers (If you have -7 + 3 it equals -4, but -3 + 7 = 4)
+ plus + = + (Simple)
- plus - = - (Like regular addition, except -2 + -3 would be -5)
Subtraction
- minus + = - (If you have -7 - 3 it equals -10, and -3 - 7 = -10)
- minus - = + (If you have -3 - (-4) = 1)
+ minus + = - or + depending on the numbers ( If you have 8 - 4 it equals 4, but if you subtract 8 from 4, it is -4
