Directions: Kindly solve the following questions and choose an option as your answer for each.
If + means ÷, − means ×, × means +, ÷ means −, give the value for 45 + 9 − 3 × 15 ÷ 2 = ?
Options
- A40
- B36
- C556
- D28
Correct answer
D. 28
Step-by-step solution
| + → ÷ | − → × |
| × → + | ÷ → − |
45 + 9 − 3 × 15 ÷ 2 = ?
→ ? = 45 ÷ 9 × 3 + 15 − 2
→ ? = 5 × 3 + 15 − 2
→ ? = 15 + 15 − 2
→ ? = 30 − 2
→ ? = 28.
Hence, the option D is correct.
