-1 times -1 times -1 times -1equals?

Answer 1

That means negative, so it is probably negative 4 which is like this. -1 -1 -1 -1= -4

Multiplying a number by a negative number changes the sign, while multiplying by 1 just keeps it at the same number.

-1*-1*-1*-1

1*1

1

The answer is 1.

The product of -1 multiplied by itself four times is 1.
