The neural-network arithmetic to solve nonlinear systems was traversed. The convergence theorem of the arithmetic was presented and proved. This theorem gives theory gist to learning rate range. The local teeny problem of the BP arithmetic is overcome. The application examples are provided. The results show that the neural network can converge to a real solution stably for an arbitrarily given initial point of nonlinear systems of equations. The precisi.on can be controlled and the high precision, solution can be obtained. Therefore, this neural network arithmetic is effective. Furthermore, the arithmetic can also solve nonlinear equations in many variables and linear systems of equations.
