Question

Indicate what each of the following arithmetic expressions evaluates to.

A. 28 / 4 − 2

B. 6 + 12 x 2 − 8

C. 4 + 8 x 2

D. 6 + 17 % 3 – 2

Answer 1

The expressions are evaluated following the order of operations, resulting in A: 5, B: 22, C: 20, and D: 6.

Step-by-step explanation:

When evaluating arithmetic expressions, it is important to follow the order of operations. Here are the evaluations for the given expressions:

• • A. 28 / 4 − 2: First, divide 28 by 4 to get 7, then subtract 2 to get 5.
  • B. 6 + 12 x 2 − 8: Following the order of operations, multiply 12 by 2 to get 24, add 6 to get 30, then subtract 8 to get 22.
  • C. 4 + 8 x 2: First, multiply 8 by 2 to get 16, then add 4 to get 20.
  • D. 6 + 17 % 3 − 2: First, find the remainder of 17 divided by 3, which is 2 (since 17 = 5*3 + 2), add 6 to get 8, then subtract 2 to get 6.
• Here's a summary of the results:
• 
  

• A: 5
• B: 22
• C: 20
• D: 6
