Remember to follow the rules within this order:
PEMDAS, Left -> right.
24 − 6 × 3 + 5^2 − (16 ÷ 2)
First, solve the parenthesis
16/2 = 8
24 - 6 x 3 + 5^2 - 8
Next, solve for the exponent
5^2 = 5 x 5 = 25
Next, multiply
24 - (6 x 3) + 25 - 8
24 - 18 + 25 - 8
Combine like terms
24 - 18 + 25 - 8 = 23
23, or (B) is your answer
hope this helps
