Question 1: What is the value of 2³ × 3²?
- 72 (Correct answer)
- 36
- 48
- 54
Correct answer: 72
2³ = 8 and 3² = 9, so 8 × 9 = 72.

- 9 (Correct answer)
- 7
- 11
- 9.5
Correct answer: 9
The median is the middle value of an ordered set; the middle of 5 values is the 3rd, which is 9.
Question 4: Evaluate: −4 + (−6) − (−3)
- −7 (Correct answer)
- −13
- 7
- −1
Correct answer: −7
−4 + (−6) − (−3) = −4 − 6 + 3 = −7.
Question 5: What is 2/5 of 75?
- 30 (Correct answer)
- 25
- 35
- 15
Correct answer: 30
2/5 × 75 = 150/5 = 30.
Question 6: Simplify: 18/24
- 3/4 (Correct answer)
