  • 11 × (8 − 5) − 9 = 24Steps
    1. 8 − 5 = 3
    2. 11 × 3 = 33
    3. 33 − 9 = 24
  • 9 − 5 × (8 − 11) = 24Steps
    1. 8 − 11 = -3
    2. 5 × -3 = -15
    3. 9 − -15 = 24
  • 9 + 5 × (11 − 8) = 24Steps
    1. 11 − 8 = 3
    2. 5 × 3 = 15
    3. 9 + 15 = 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.
