The Joy of Arithmancy

I've been studying arithmancy, doing exercises for it all morning, and I have a tutoring session with Mr. Wilkes tomorrow.

I'm not as bad off as I feared; I've been doing enough magic using advanced forms of arithmancy that I at least know the forms and can do some of them. Any spell employing motion or ballistics requires some form of calculus or differential equations, so what I haven't had in book-learning, I've had in practise.

The neat thing about arithmancy is that it ties all the other forms of magic together and can explain the results attained in all of them. It's the key to everything.
