I think I'm done. I can now write this after the other WHOLE page of stuff I can write off the top of my head:

"Differential Calculus is the arithmetic of infinitely small differences of variable quantities.

Integral Calculus is the deduction of magnitudes from the ratio of small changes of other magnitudes."

So, two sentences in one evening isn't very impressive, but it's progress. I'm exhausted after a week of work and school. I still need to memorize 3 descriptions of each of the types of Calculus, but it's not happening tonight. 😕 I also didn't do any math, but it's easier to remember words when I'm tired than new-ish math concepts.

Gotta get my brain working this weekend! Blegh. Wish me luck.
