Answer:
63
Step-by-step explanation:
Follow PEMDAS, as well as the left -> right rule.
Note that PEMDAS is the order of operations in which you should solve, and =
Parenthesis
Exponents (& roots)
Multiplication
Division
Addition
Subtraction.
First, look at the problem. The problem gives you:
42 ÷ 2 x (11 - 8)
Using PEMDAS, first, solve the parenthesis:
11 - 8 = 3
Next, use the left -> right rule to solve the rest.
42 ÷ 2 x 3
(42 ÷ 2) x 3
(21) x 3 = 63
63 is your answer.
