  2. 3 × -4 = -12
  3. 12 − -12 = 24

4 solutions

  • 3 × (12 + 7 − 11) = 24Steps
    1. 7 − 11 = -4
    2. 12 + -4 = 8
    3. 3 × 8 = 24
  • 12 + 3 × (11 − 7) = 24Steps
    1. 11 − 7 = 4
    2. 3 × 4 = 12
    3. 12 + 12 = 24
  • (3 + 11) ÷ (7 ÷ 12) = 24Steps
    1. 3 + 11 = 14
    2. 7 ÷ 12 = 7/12
    3. 14 ÷ 7/12 = 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.
