4 4 8 10 = 24: 4 solutions

Difficulty: HardOpen in Solver

4 × (10 + 4 − 8) = 24

  1. 4 − 8 = -4
  2. 10 + -4 = 6
  3. 4 × 6 = 24

4 solutions

  • 4 + 10 ÷ (4 ÷ 8) = 24Steps
    1. 4 ÷ 8 = 1/2
    2. 10 ÷ 1/2 = 20
    3. 4 + 20 = 24
  • (4 − 8) × (4 − 10) = 24Steps
    1. 4 − 8 = -4
    2. 4 − 10 = -6
    3. -4 × -6 = 24
  • (8 − 4) × (10 − 4) = 24Steps
    1. 8 − 4 = 4
    2. 10 − 4 = 6
    3. 4 × 6 = 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.
