1 3 3 8 = 24: 3 solutions

Difficulty: EasyOpen in Solver

3 × (1 + 8) − 3 = 24

  1. 1 + 8 = 9
  2. 3 × 9 = 27
  3. 27 − 3 = 24

3 solutions

  • 3 − 3 × (1 − 8) = 24Steps
    1. 1 − 8 = -7
    2. 3 × -7 = -21
    3. 3 − -21 = 24
  • 3 + 3 × (8 − 1) = 24Steps
    1. 8 − 1 = 7
    2. 3 × 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.
