Worked examples
Calculate: 348 + 174
- 422
- 522
- 512
- 412
Answer: 522. 8 + 4 = 12 (write 2, carry 1). 4 + 7 + 1 = 12 (write 2, carry 1). 3 + 1 + 1 = 5.
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.
