We first give a local convergence ball for multistep simplified New-ton-like methods for solving nonlinear equations with nondifferentiable operators. Next we apply the results to some iterative methods and derive Rheinboldt’s ball for Newton's method. Rall's result for Newton’s method is also extenciec to the multistep simplified Newton method. Furthermore, we use Rall's example to see how the size of the convergence ball varies along with the multistep number.
