4 5 7 13 = 24: 3 solutions

Difficulty: HardOpen in Solver

(5 + 7 × 13) ÷ 4 = 24

  1. 7 × 13 = 91
  2. 5 + 91 = 96
  3. 96 ÷ 4 = 24

3 solutions

  • (4 − 7) × (5 − 13) = 24Steps
    1. 4 − 7 = -3
    2. 5 − 13 = -8
    3. -3 × -8 = 24
  • (7 − 4) × (13 − 5) = 24Steps
    1. 7 − 4 = 3
    2. 13 − 5 = 8
    3. 3 × 8 = 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.
