1 6 6 8 = 24: 1 solution
6 ÷ (1 − 6 ÷ 8) = 24
- 6 ÷ 8 = 3/4
- 1 − 3/4 = 1/4
- 6 ÷ 1/4 = 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.
This hand needs fraction intermediates: the classic shape is a ÷ (b − c ÷ d) — build a fraction first, then multiply it back to 24.
