  • 10 + 2 × (1 + 6) = 24Steps
    1. 1 + 6 = 7
    2. 2 × 7 = 14
    3. 10 + 14 = 24
  • 6 − 2 × (1 − 10) = 24Steps
    1. 1 − 10 = -9
    2. 2 × -9 = -18
    3. 6 − -18 = 24
  • 6 + 2 × (10 − 1) = 24Steps
    1. 10 − 1 = 9
    2. 2 × 9 = 18
    3. 6 + 18 = 24
  • 6 × (10 ÷ 2 − 1) = 24Steps
    1. 10 ÷ 2 = 5
    2. 5 − 1 = 4
    3. 6 × 4 = 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.
