4 9 11 12 = 24: 3 solutions

Difficulty: HardOpen in Solver

12 × (4 + 9 − 11) = 24

  1. 4 + 9 = 13
  2. 13 − 11 = 2
  3. 12 × 2 = 24

3 solutions

  • 12 ÷ (4 ÷ 11) − 9 = 24Steps
    1. 4 ÷ 11 = 4/11
    2. 12 ÷ 4/11 = 33
    3. 33 − 9 = 24
  • 4 × 12 ÷ (11 − 9) = 24Steps
    1. 4 × 12 = 48
    2. 11 − 9 = 2
    3. 48 ÷ 2 = 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.
