Learning vs Understanding

I finally learned how to solve a Rubik's cube without any cheat sheets.

But I am not quite happy.

Because I learned how to solve it and do not understand why the moves solve it.

So frustrating.

So guess who is now studying permutation groups :-D

I'm not sure if understanding the Rubik's group will help me understand the moves, but hey, one step at a time. 

And one cube type at a time ;-)
