1 3 6 13 = 24: 2 solutions

Difficulty: HardOpen in Solver

3 × (13 + 1 − 6) = 24

  1. 1 − 6 = -5
  2. 13 + -5 = 8
  3. 3 × 8 = 24

2 solutions

  • (13 − 1) ÷ (3 ÷ 6) = 24Steps
    1. 13 − 1 = 12
    2. 3 ÷ 6 = 1/2
    3. 12 ÷ 1/2 = 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.
