1 6 6 9 = 24: 1 solution

Difficulty: MediumOpen in Solver

6 × (9 + 1 − 6) = 24

  1. 1 − 6 = -5
  2. 9 + -5 = 4
  3. 6 × 4 = 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.
