One day, the teacher inquired of Peter:" How much is four minus four?" Peter was tongue-tied. The teacher got angry and said: "What a fool! You see, if I put four coins in your pocket, but there is a hole in your pocket and all of them leak out, now what is left in your pocket?" "The hole," replied Peter.一天，老师问皮特：“4减4等于几？”皮特缄口了。老师很生气得说：“真是笨啊，如果我在你口袋里放4个硬币，但你的口袋有个洞，而且所有硬币都掉光了。那么现在你口袋里还有什么？”“破洞！”皮特回答。
