How to play
- Put every sign from the tray into the gaps to make a true equation. Each sign is used once, and there is exactly one =.
- Normal order of operations: × and ÷ before + and −.
- Every step must stay a whole number, zero or more. No fractions, no negatives.
- Tap a gap, then tap a sign. Tap a placed sign to take it back.
- Fill every gap, then Check. You get 3 checks. Your score is checks plus hints, like golf: beat the par.
