# My First Wiki - Vandermonde's Identity

I decided to combine my article writing with wikis by adding them to the Brilliant Wiki.

So, here's my first wiki on Vandermonde's Identity

I found some discussions on Brilliant regarding this identity, where students asked for the explanation, so I decided to add them up to the wiki. I hope, you all will like it.

I would appreciate if you can edit the wiki to make it better.

Thanks,

Ah, I remember the day I first learn about Vandermonde's Identity (combinatorial proof), and it was amazing!

Yea, Combinatorics is amazing! In fact, I find the dual counting (counting in two different ways) to be the best part of it.
