Make 24 with 1, 1, 1, 1

The 24 Game hand 1, 1, 1, 1: use each digit exactly once with + - × ÷ and parentheses to reach exactly 24. This hand cannot make 24 — the solver checked every possible expression with + - × ÷ and parentheses using exact fraction arithmetic, so that is a proof, not a shrug.

Why 1, 1, 1, 1 is impossible

No combination of 1, 1, 1, 1 with + - × ÷ and parentheses equals 24. Four numbers and four operations make a small, finite space of expressions; the solver evaluated all of them with exact fractions and none reached 24. That is a checked mathematical fact — this hand is famous precisely for being a lost cause.
