First, applications of the method to algebraic equations are discussed and some new root-finding algorithms developed by this method are given. Next, the applications of the new method to first order, second order and systems of first order ordinary differential equations are discussed. Three sample problems are selected. Results are compared with analytical solutions, solutions by other methods and numerical solutions. The new perturbation iteration method is an effective method that does not require small parameter assumption as in classical perturbation methods.EnglishAll Open Access; Gold Open AccessAlgebraIntegral equationsIterative methodsNumerical methodsOrdinary differential equationsAlgebraic equationsFirst order ordinary differential equationsIteration algorithmsIteration methodNumerical solutionPerturbation methodRoot finding algorithmsSecond ordersPerturbation techniquesReview10.3390/mca18030139
