I am a PhD in Mathematics at the Université de Montréal. I have a math blog in case anyone's interested!

Some of my favourites among the answers I gave on MSE-

1. Number of integer solutions of $a^2+b^2=10c^2$

2. Sumsets are minimized by Arithmetic Progressions

3. An alternative solution for $\int_0^{\frac \pi 2}\sin(2nx)\cot x \text{ d}x$

4. Prove that $n^n<(n!)^2$ for $n>2$

5. Find the smallest natural number $n$ such that every $n$-element subset of $S = \{ 1,2,\dots ,280\}$ contains $5$ pairwise relatively prime numbers

Some of my answers that (I believe) didn't get enough attention simply because they were too late to the party-

1. A simple way to obtain $\prod_{p\in\mathbb{P}}\frac{1}{1-p^{-s}}=\sum_{n=1}^{\infty}\frac{1}{n^s}$

2. Intuition for Prime Number Theorem

3. Why is Euler's Totient function always even?

4. Ring of quaternions over $\mathbb Z_3$

5. Gauss's Lemma Proof

Some of my questions that got some brilliant answers-

1. Intuition behind Newton's Interpolation methods

2. Symmetries of Persian tiles

3. Proof of Stewart's Theorem using elementary geometry
