3 solutions

  • (3 − 7) × (5 − 11) = 24Steps
    1. 3 − 7 = -4
    2. 5 − 11 = -6
    3. -4 × -6 = 24
  • (7 − 3) × (11 − 5) = 24Steps
    1. 7 − 3 = 4
    2. 11 − 5 = 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.
