  • 6 − 9 × (9 − 11) = 24Steps
    1. 9 − 11 = -2
    2. 9 × -2 = -18
    3. 6 − -18 = 24
  • 6 + 9 × (11 − 9) = 24Steps
    1. 11 − 9 = 2
    2. 9 × 2 = 18
    3. 6 + 18 = 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.
