Question

The sign of the product of two integers with the same sign is positive. What is the sign of three integers with the same sign? Explain your thinking.

Answer 1

Can be both, because if all three were negative, it would be

negative*negative= positive
positive*negative=negative
example: -1*-1*-1=-1

but if all three were positive, it would obviously be positive, because any number of positives can't make negatives in multiplication.
