These tenses are formed using different auxiliary verbs: "will/shall" for future simple, "will be/shall be" for future continuous, and "will have/shall have" for future perfect. Negative sentences and questions involve placing "not" after the auxiliary or inverting the auxiliary and subject, respectively.
