An algebraic approach to the theory of countable functions is given. Compositions (superpositions) of functions are used instead of recursions. Arithmetic and analytic algorithms are defined. All closed sets are founded. Mathematically precise definitions of logic algorithms with quantifiers of existence and universality are given. Logic algorithm for fast-growing function is built as example. Classification of functions is given. There are non-computable functions. These functions are fictitious (useless) and their set is continual. The set of computable functions is countable. Incompleteness of disjunction and negation, conjunction and negation, of Pierce, Sheffer and diagonal Webb functions is proved. The completeness of the set of one-place functions and any all-valued essential function (Slupecki theorem) is proved for computable functions. Existence of generators of all computable functions is proved too.
