[quote=Anonymous]I have a math degree and I don't know the "8 major rules of exponents". I know that exponentiation is essentially repeated multiplication, and I can work out the consequences as needed, because I understand multiplication. I have certainly unintentionally memorized some things, but never intentionally. I've occasionally tried. It doesn't work. Learning is working with things until the ideas sink in. There is a small collection of vocabulary words to memorize, but that is not why people have trouble with math, and if you "memorize" them intentionally, you are skipping the *doing math* that makes the ideas stick. Maybe you are using "memorize" to mean "learn"? PV=nRT is a great example. If you know what P, V, N, rR, and T mean, you don't need to memorize the formula, because it's intuitively obvious. If you try to memorize the formula, you will fail understanding chemistry. [/quote]
