Answer:
It isn't too tricky to perform operations using positive and negative numbers with zero. You follow normal addition and subtraction rules, and what zero does to the final sign depends on where the zero is. When you multiply or divide using zero, that zero just wipes out the numbers and leaves you with zero.
