A Superficial Proof of Fermat's Last Theorem
I mentioned my interest in learning about Fermat's Last Theorem in an earlier post. As I wrote in that post, the theorem is surprisingly simple to state but the proof required …

The Marriage Lemma is a neat result that has the following interesting formulation: Consider a group of men and women in a party. Suppose in any group of n men, there …
The Principle of Mathematical Induction is arguably one of the most powerful techniques in mathematics. Formally, the principle asserts the following: Principle of Mathematical Induction: Consider a set of statements …
The pigeonhole principle is based on a very simple idea but is very powerful in mathematical problem solving. Here is the principle: Pigeonhole Principle: If there are objects to …
One of my favourite tricks in mathematical problem solving is the idea of a telescoping series. Consider the following problem: Find the sum of This seems to lead to …
One of the most famous stories in mathematics is related to Gauss when he was a little boy. It went as follows: "It was said that to punish the kids …
Calculate the area of the shaded region. There are many solutions to this problem. One can divide the shaded region into triangles and sum these areas. Alternatively, one might deduct …
One of the most fascinating features of mathematics is that many theorems are so simple to state but so difficult to prove. A prime example is Fermat's last theorem. …
Prime numbers fascinate me. They are essentially the building blocks for multiplication. Recall that a positive integer is prime if the only positive integers dividing into are none other than 1 …
I have always maintained an interest in mathematics. In this blog, you will see some of my thoughts on this subject. Most people tend to think of mathematics as a …
