### Excerpt: Memorizing Versus Understanding (p. 129)

Memorizing mathematics without comprehension is often harmful. If you memorize a poem that you don't understand, there is still the chance that the flow of the words may have an effect on you. When you memorize dates of historical events, at least you know the chronological order of those events, even if you may not know their significance. When you memorize mathematics without understanding, you delude yourself into thinking that you know something, when in fact you do not. This delusion compounds the lack of understanding. Your ability to apply the knowledge, generalize it, or even question its truth is compromised.
