  • 4 × (13 + 3 − 10) = 24Steps
    1. 3 − 10 = -7
    2. 13 + -7 = 6
    3. 4 × 6 = 24
  • 4 × 10 − (3 + 13) = 24Steps
    1. 4 × 10 = 40
    2. 3 + 13 = 16
    3. 40 − 16 = 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.
