We present the main features of the mathematical theory generated by the \kappa-deformed exponential function exp_{ \kappa}(x)=(\sqrt{ 1+\kappa^2 x^2}+\kappa x)^{ 1/\kappa}, with 0<\kappa<1, developed in the last twelve years, which turns out to be a continuous one parameter deformation of the ordinary mathematics generated by the Euler exponential function. The \kappa-mathematics has its roots in special relativity and furnishes the theoretical foundations of the \kappa-statistical mechanics predicting power law tailed statistical distributions which have been observed experimentally in many physical, natural and artificial systems. After introducing the \kappa-algebra we present the associated \kappa-differential and \kappa-integral calculus. Then we obtain the corresponding \kappa-exponential and \kappa-logarithm functions and give the \kappa-version of the main functions of the ordinary mathematics.
