Make 34 with four 4s
The classic four fours puzzle: build an expression from exactly four 4s that equals 34. 34 cannot be made with + - × ÷ alone (the solver checked every expression) — you will need to stick 4s together (like 44) or use decimals (like .4).
Solutions using only + - × ÷
No expression made of four plain 4s and + - × ÷ reaches 34 — the solver checked every possible expression.
Solutions with concatenation and decimals
44 - 4 / .4 = 34
Solutions with square roots, factorials, exponents
4! + 4 + 4! / 4 = 344! / 4 + 4 + 4! = 344 + 4! + 4! / 4 = 34.4 × 4! + .4 + 4! = 34.4 + .4 × 4! + 4! = 34
…and 74 more at this tier.
80 distinct solutions found in total, after removing trivial rearrangements.
How 34 compares
34 has 80 distinct solutions across all three tiers — #43 most plentiful of the 95 solvable targets. Next door, 33 has 4 solutions and 35 has 17 solutions. The nearest impossible target is 73, 39 away — proven unreachable, not just unsolved.
If 34 went down easily, make 33 with four 4s — 4 solutions, the nearest step up in scarcity.
