Hi, I'm a bit new to this place.

I was thinking about this equation for a while. It came up because I've been doing excessive fraction work in Kumon lately (Urrrgh not Kumon). Essentially, you could say I "discovered" it?

So, I was asking if anyone could prove, if possible:

For all values of N (Natural numbers).

I've been assuming this equation for a while to help me take shortcuts in Kumon, but I was wondering if it is even true?

Post your proofs, or proofs against this equation, below.

Hi Cam9430;

That is an identity, it is true for all numbers not just N.

Have you encountered partial fractions before?

This is clearly true as you claimed, since
