Custom puzzle

Set your own target, numbers and operations. Uses the toggles above. We’ll check that it’s solvable.

Combine the numbers with + − × ÷ ^ and parentheses to hit the target. Every digit is a single number — no gluing 1 and 2 into 12. Division must come out whole, powers (^, from Medium up) need an exponent ≥ 0, and there’s no negative sign (but subtraction can go below zero). Type * or x for ×, / for ÷, ^ for powers. Enter submits, Alt+R re-rolls.
