Melbet

Melbet is a place to explore Boolean logic with two inputs. Toggle A and B to see how AND, OR, XOR and NOT change the result. Build expressions with token buttons and parentheses, using up to two operators. Read correction messages for incomplete expressions and follow how each operation evaluates. Start with six bundled examples, from simple gates to grouped expressions. Open an example in Compose, change its inputs and explore the effect of NOT or different grouping. View all four input combinations in a truth table. Select a row to see its intermediate steps, operator rules and final result, including explanations when an input is unused. Work offline and save named expressions with their input values locally on your device. Open full details, edit saved work or confirm its deletion in Melbet.
