Show answer and solution
Correct answer: A. 17
Division and multiplication go left to right first: 12 ÷ 4 = 3, then 3 × 3 = 9, and 8 + 9 = 17.

Find 48 ÷ 6 ÷ 2, working left to right.
- 16
- 2
- 12
- 4
Show answer and solution
Correct answer: D. 4
48 ÷ 6 = 8 and 8 ÷ 2 = 4; grouping the other way would wrongly give 16.
Evaluate 100 - 4 × 5 + 10 ÷ 2.
- 85
- 105
- 45
- 75
Show answer and solution
Correct answer: A. 85
Multiplication and division first give 20 and 5, so 100 - 20 + 5 = 85.
