The rule is whenever a negegative number is multiplied by another negative number the answer is always positive.
Whenever you multiply an odd number of negative numbers the answer is always negative. Whenever you multiply an even number of negative numbers the answer is always positive. I hope this helped, God Bless.

No, -2x-2 is positive 4. Then 4x-2 is negative 8.

No.
(-2)^3 = (-2) * (-2) *(-2).
(-2) * (-2) = +4, so that (-2)^3 = +4 *(-2) = -8

TWO negatives make a positive. You have THREE negatives, so it stays negative.
(-2)(-2)(-2)
= (4)(-2)
= -8

NO...if it wud have been -2^2..then positive. but if its uneven number such as 3....then it is negative again. sume examples below:
-2 x -2 =4 (even times multiplied)
-2 x -2 x -2 =-8 (uneven times multplied)
-2 x -2 x -2 x -2 =16 (even times multplied)
the next you can guess
-2 x -2 x -2 x -2 x -2 = ?

No because as you multiply you cancel out the positive and negatives so after 2 negatives its positive but adding the third negative make it negative.
