$-100 - (-5)^3$; The simplified form of the expression is equal to $25$.
The cube of $-5$ is $(-5)^3$. Subtracting this to $-100$ gives: $-100 - (-5)^3$ The order of operations states that to simplify the expression, the exponent must be applied first before the subtraction is performed. Thus, $-100-(-5)^3 = -100-(-125) =-100+125 = 25$
