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(gè)小的社區(qū)大學(xué)教基礎(chǔ)數(shù)學(xué)。我把這門課的一部分稱為在現(xiàn)實(shí)生活中的實(shí)際運(yùn)用。在我教完單利和復(fù)利這一課的第二天,一個(gè)學(xué)生在門廊里追上我說(shuō):“昨天你真的給我的生活上了一堂課。讓我明白,這30年來(lái)我一直過著缺乏興趣、天天惡化的生活。”(interest:利息、興趣;compound:復(fù)合、惡化)
