Bombanana Numpad Calculator
module 02 / solve the math / odd-even · vs 5 · LED branch
Data v0.1.0, checked 2026-07-02. Demo coverage; rules appear only when two independent sources agree.
The numpad module shows an arithmetic expression, but the raw result is not the key you press. The result gets classified odd or even and greater or less than 5, an LED color picks the manual branch, and the keypad is jumbled so only the printed number matters.
This calculator does the math and the classification instantly and warns when two branches collide. Full rule: numpad in the manual.
