Answer:

  A)  B. 18-6

  B)  20÷4

  C)  20

Step-by-step explanation:

Part A

The order of operations tells you that the first step is to evaluate any expressions in parentheses. Here, that means you first evaluate (18 -6).

__

Part B

After parentheses have been removed, the next step is to perform multiplication and division. Here, there is only one term involving division, so you divide 20 by 4 as your second step.

__

Part C

After you have done parts A and B, your expression is ...

  3 + 12 + 5

The value of this sum is 20.
