Basic Math is the subject I teach at a small community college. I call one part of the curriculum Practical Applications for Living in the Real World. The day after I presented a lesson on simple and compound interest, one of my students approached me in the hallway. “You really taught me a great deal about my life yesterday,” he said. “I realized I've been struggling with a lack of interest, compounded daily, for thirty years.”
我在一個小的社區(qū)大學教基礎(chǔ)數(shù)學。我把這門課的一部分稱為在現(xiàn)實生活中的實際運用。在我教完單利和復利這一課的第二天,一個學生在門廊里追上我說:“昨天你真的給我的生活上了一堂課。讓我明白,這30年來我一直過著缺乏興趣、天天惡化的生活?!保╥nterest:利息、興趣;compound:復合、惡化)
