Worked examples
Calculate: 240 × 5
- 1200
- 1020
- 1250
- 120
Answer: 1200. 240 × 5: think 24 × 5 = 120, then × 10 = 1200.
Complete the step: 84 − 37 = 84 − 40 + ___.
- 3
- −3
- 37
- 30
Answer: 3. We subtracted 40 instead of 37 — that's 3 too many. Add 3 back. 84 − 40 = 44; 44 + 3 = 47.
Why does (12 × 4) ÷ 2 give the same answer as 12 × 2?
- Because ÷ 2 and × 2 are inverse operations, so × 4 then ÷ 2 is the same as × 2.
- Because both equal 24 by coincidence.
- Because 12 is even.
- Because of the order of operations.
Answer: Because ÷ 2 and × 2 are inverse operations, so × 4 then ÷ 2 is the same as × 2.. × 4 is the same as × 2 × 2. Then ÷ 2 cancels one of the × 2. Result: × 2.
