Question

Which multiplication has a negative answer?

A) (-1)(-1)
B) (-1)(-1)(-1)(-1)
C) (-1)(-1)(-1)(-1)(-1)
D) (-1)(-1)(-1)(0)

Answer 1

i'm pretty sure it's C

-1 times -1 becomes positive, and then times -1 again, it's negative, and times it again, it's positive, and THEN one more time (lol) it's -1.

Answer 2

The correct answer is D
