Boolean algebra and digital logic, explained — with live examples you can build yourself.
An introduction to Boolean algebra: variables, the three core operations, and the laws that let you simplify any logical expression.
5 minWhat a truth table is, how to build one by hand, and how it connects directly to logic gates and circuit verification.
4 minHow De Morgan's laws let you convert any AND/OR expression into an equivalent built entirely from NAND or NOR gates.
No install. No account. Just open the editor and start placing gates.
