| Abstract: | The Monte-Carlo method, which is a stochastic simulation method, is introduced. The fundamental idea of the Monte-Carlo method is expounded by Buffon needle problem. Apply this method to the integral calculation, and give the formula of "separation of principal part" in integral and show an example. |

| Keywords: | stochastic simulation uniform distribution random number integral |
