This paper proposes a complete elementary without reference to other sources (except for Euler), first proof of the Fermat's Last Theorem. We resolve the question of the ambiguous expansion in the Binomial theorem, Resolved the question of the ambiguity certain infinite sequences of the Euler. Given other versions proof of FLT, We consider and solve the question of not available modern geometric representation of continuous functions without derivatives at any point.
