How do I solve this?

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.

Answer:
42 ÷ 2 × (11 - 8) = 63
Step-by-step explanation:
When solving a problem like this you have to go in PEMDAS order.
First is Parentheses :
42 ÷ 2 × (11 - 8)
42 ÷ 2 × ( 3 )
Second is Exponents(here is none) :
42 ÷ 2 × ( 3 )
Next is Multiplication and Division, In this problem it would be division first. These 2 always go in left to right order which ever come first you do that first. :
42 ÷ 2 × ( 3 )
21 × ( 3 )
63
The last one is addition and subtraction which is the same as multiplication and division. (In this case there is none)
You are finished
