In math, there are often many roads to the same destination, and some roads are much nicer than others. In this post, we find the first derivative of $\prod _{i=1}^n{f}_i(x)$ two different ways: one direct and tedious, the other initially unintuitive but elegant.

In this post, I give a reader-friendly primer on “reduction”, a computer scientist’s tool for relating problems to one another. I then solve the Molecube puzzle by reducing it to the Rubik’s cube.
