Worked practice questions
A calculator follows BODMAS. What does it show for 1 + 2 × 3?
- 9
- 6
- 5
- 7
Show answer and solution
Correct answer: D. 7
Multiplication outranks addition, so 2 × 3 = 6 is done first and then 1 + 6 = 7.
Evaluate the bracketed expression (2 + 3) × 4 using the usual rules.
- 14
- 24
- 20
- 10
Show answer and solution
Correct answer: C. 20
The bracket gives 5 first, and 5 × 4 equals 20.
