I'm not sure where, but I remember reading something like that somewhere. It said 'mathematics should be read both forwards and backwards' or 'maths books should be read both forwards and backwards' or some variation of that, but I'm not sure exactly. I also remember it sort of had something to do with Lagrange, but whether he's the one who said it, I don't know. Does anyone know the exact quote or the person who said it?
