Question

Simplify: -2(-3+2) - 3(3-4)^3 - 9^2 please show work

Answer 1

First solve the numbers inside the quotes... so for (-3+2), you get -1.
Then solve the powers (assuming you know simple multiplication)
Then you do the multiplications (i.e.) -2(whatever is inside)
Then you subtract or add.

Its all about orders of operations

Answer 2

You cannot distribute the -3 into the 3 and -4.
You have to solve the power first, which means you have to solve the inside of the parenthesis first.

Answer 3

-2(-3+2) - 3(3-4)^3 - 9^2
= -2(-1) - 3(-1)^3 - 81
= 2 + 3 - 81
= -76
