3 3 7 7 = 24: 1 solution
7 × (3 + 3 ÷ 7) = 24
- 3 ÷ 7 = 3/7
- 3 + 3/7 = 24/7
- 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.
