Worked examples

RookieRead and interpret directly.

Calculate: 240 × 5

  • 1200
  • 1020
  • 1250
  • 120

Answer: 1200. 240 × 5: think 24 × 5 = 120, then × 10 = 1200.

ProCompare and infer.

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.

GuruMulti-step reasoning.

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.
