The Monte Carlo simulation method and its mode of actions in different processes are introduced. This article addresses some answers to some frequent questions raised by students of chemical and polymer engineering on Monte Carlo simulation methods. The interesting name on this method and the extraordinary developments in both soft and hardware facilities in computer world encourage the researchers to explore and solve complex problems using this method. Consequently, the increase in the number of research areas in academic centers focuses on the stochastic and especially on the Monte Carlo methods. The fundamental issues and requirements are presented for how to begin the Monte Carlo simulation method. A little historical origin and a detailed example are given as standard reference for students who are willing to pursue their research on Monte Carlo simulation methods.
