#### Approximate Pi: Matlab Monte-Carlo Method

We approximate pi using a Monte-Carlo method in Matlab, explain the code, provide the program for you to try for yourself, and present an error analysis.

The Math Section is the host for the Carnival of Mathematics #163.

This article serves as a follow-up to the article titled Friendship Paradox. We consider the complement graph which creates the Inverse Friendship Paradox.

We prove that vampires are a mathematical impossibility due to the properties of exponentially growing functions.

We present an example of a problem from theoretic computer science and epistemic logic, the Byzantine general problem.

This is a book review of the book How to Solve It. The article gives insight into how the book can help both mathematicians and non-mathematicians improve their problem-solving skills.
