Evaluate: -7 - 8
In math evaluating is where you simplify an expression as much as possible. For example to evaluate 5+2 you simplify it so it is 7. To evaluate 5x+3x+4y you simplify it to 8x+4y.
Evaluate -6 to the power of 2
What is 1+2 with sum
5
evaluate means the same thing as solve in most math terms so9^2= 81
Multiply the "copies" of term according to the power. For instance: 25 = 2 x 2 x 2 x 2 x 2 = 32
Evaluate: -7 - 8
[10-(4*2)]*3

A variable raised to the second power would be refered to as "squared." Some math-based programs like Excel let you enter a power with a carot, ie, "(variable name)^2" if you want to calculate the answer.
what is 7x to the third power + 6x to the second - 2
