systems to process sentences in a natural
language such as English, rather than in a
specialized artificial computer language.
mathematical statement or simply a statement is a
meaningful composition of words which can be
considered either true or false. The mathematical

unambiguous, which means that any statement has
exactly one meaning, regardless of context.
