6 solutions

  • 5 × 6 − 1 × 6 = 24Steps
    1. 5 × 6 = 30
    2. 1 × 6 = 6
    3. 30 − 6 = 24
  • 5 × 6 − 6 ÷ 1 = 24Steps
    1. 5 × 6 = 30
    2. 6 ÷ 1 = 6
    3. 30 − 6 = 24
  • 6 ÷ (1 ÷ 5) − 6 = 24Steps
    1. 1 ÷ 5 = 1/5
    2. 6 ÷ 1/5 = 30
    3. 30 − 6 = 24
  • 1 × (5 × 6 − 6) = 24Steps
    1. 5 × 6 = 30
    2. 30 − 6 = 24
    3. 1 × 24 = 24
  • (5 × 6 − 6) ÷ 1 = 24Steps
    1. 5 × 6 = 30
    2. 30 − 6 = 24
    3. 24 ÷ 1 = 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.
