Truth table

A truth table is a mathematical table used in logic to compute the functional values of logical expressions on each of their functional arguments, that is, on each combination of values taken by their logical variables.

In particular, truth tables can be used to tell whether a propositional expression is logically valid.

A truth table is composed of one column for each input variable and one final column for all of the possible results of the logical operation that the table is meant to represent.

Each row of the truth table therefore contains one possible configuration of the input variables, and the result of the operation for those values.
