  • 4 × 7 − 12 ÷ 3 = 24Steps
    1. 4 × 7 = 28
    2. 12 ÷ 3 = 4
    3. 28 − 4 = 24
  • 12 ÷ (3 ÷ 7) − 4 = 24Steps
    1. 3 ÷ 7 = 3/7
    2. 12 ÷ 3/7 = 28
    3. 28 − 4 = 24
  • 3 + 12 ÷ (4 ÷ 7) = 24Steps
    1. 4 ÷ 7 = 4/7
    2. 12 ÷ 4/7 = 21
    3. 3 + 21 = 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.
