Annotation: The numerical methods for solving nonlinear equations with minimization of function of several variables, which are result of Taylor expansion of the inverse function, are investigated. An algorithm allowing to obtain the iterative procedures with more higher order of the convergence, which include the function values and its first derivative only, is suggested.
