This paper proposes a three-step method for solving nonlinear Volterra integralequations system. The proposed method convents the system to a (۳ × ۳)nonlinear block system and then by solving this nonlinear system we ndapproximate solution of nonlinear Volterra integral equations system. To showthe advantages of our method some numerical examples are presented.
