2 6 6 7 = 24: 3 solutions

Difficulty: EasyOpen in Solver

6 × (7 − 6 ÷ 2) = 24

  1. 6 ÷ 2 = 3
  2. 7 − 3 = 4
  3. 6 × 4 = 24

3 solutions

  • (6 + 6 × 7) ÷ 2 = 24Steps
    1. 6 × 7 = 42
    2. 6 + 42 = 48
    3. 48 ÷ 2 = 24
  • 6 × (7 − 2) − 6 = 24Steps
    1. 7 − 2 = 5
    2. 6 × 5 = 30
    3. 30 − 6 = 24

Solving hints

  • Build a factor pair: split the four numbers into two groups and try to make a factor pair of 24 — 3 × 8, 4 × 6, or 12 × 2 — then multiply the two groups.

  • No factor pair divides cleanly? Switch to sums: make two numbers add up to 24, or try shapes like (a ± b) × (c ± d) and (a + b + c) × d.
