1. -1+1=0?
2. 2x(-4)x(-4)x(-2)=-8 or 64
on this one i am not sure if i multiply the absolute value or multiply as is

1. 1. Yes

2. I don't know if you have the formula correctly written. Online we use an asterisk (*) to indicate multiplication rather than x, because x is often used to indicate an unknown. If your x's indicate multiplication:

2(-4) * (-4)(-2) = -8 * 8 = -64

I hope this helps. Thanks for asking.
