2 7 7 10 = 24: 1 solution

Difficulty: ExpertOpen in Solver

7 × (2 + 10 ÷ 7) = 24

  1. 10 ÷ 7 = 10/7
  2. 2 + 10/7 = 24/7
  3. 7 × 24/7 = 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.

  • This hand needs fraction intermediates: the classic shape is a ÷ (b − c ÷ d) — build a fraction first, then multiply it back to 24.
