The binomial coefficients

In the last post, we’ve finished talking about combinations and I mentioned there that the binomial coefficient are really important, so in this post I am going to focus on them and show some great properties of them. This post is also going to be the first one that I use combinatorical proofs, they willContinue reading “The binomial coefficients”
