Answer:
The sign of the product is negative because a positive multiplied by a negative is a negative.
Explanation:

-1×-1=1
1×1=1
A negative multiplied by a positive is always negative. Doesn't matter which order you put it in. Meaning a positive multiplied by a negative is also always negative.
A positive multiplied by a positive is always positive.
