evaluate this expression.
enter the number that belongs in the green box.
$5^2 - \frac{10}{5} + 2^3 = \boxed{?}$

Explanation:

Step1: Calculate exponents first

$5^2=25$, $2^3=8$
Expression becomes: $25 - \frac{10}{5} + 8$

Step2: Perform division next

$\frac{10}{5}=2$
Expression becomes: $25 - 2 + 8$

Step3: Do addition/subtraction left to right

$25 - 2 = 23$, then $23 + 8 = 31$

Answer:

31
