The present paper proposes a fast numerical method for the linear Volterra integral equations with regular and weakly singular kernels having smooth solutions. This method is based on the approx- imation of the kernel, to simplify the integral operator and then discretization of the simplied operator using a forward dierence formula. To analyze and verify the accuracy of the method, we examine sample and benchmark problems with known exact solutions.
