Logic Calculator Free

toán mệnh đề và tính lôgic

Logic Calculator Free is an app that gives the truth value of a logical proposition from 2 different ways: you can enter the individual truth value of the variables to deliver a single truth value true or false that corresponds the whole proposition, or you can enter the logical proposition and it automatically gives a truth table with all possible combinations depending the number of variables in use. In that case the result can be a tautology, a contingency or a contradiction.

The calculator also has a comparison mode. It compares up to 3 propositions to verify their equivalency. After the verification it automatically builds the truth table of the comparison.

Supported opperations: AND, NAND, OR, NOR, XOR, IMPLICATION, BICONDITIONAL.
