How do you call the result from a logic disjunction or similar?

Question

when adding two numbers like 2 + 3 = 5 then 5 is called "sum". When doing true AND false or false NOR true then what are the names of the result of these operations? Are there any lists or references?

Answer 1

An expression like "true AND false" is called a contradiction. It always results in false. The truth table of such an expression has nothing but false/zero values as output. An alternative term is paradox.

The opposite is called tautology, an expression or formula which always results in true.
