记得小学一年级时,在一节数学课上,数学老师给我们出了一道特别有趣的题目:一位渔翁钓鱼,钓了6条没头的,9条没尾的,8条半截的,共钓了多少条鱼?许多同学异口同声地当场回答;6+9+8,共钓23条鱼。老师摇摇头说:不对,请同学们再想想!教室里鸦雀无声,每个人都在积极思考。我一边深入地想,一边用手指在桌上写划,猛开心窍,立即回答:这位渔翁一条鱼也没钓着,得数是“0”。
I remember the first grade of primary school, mathematics teacher in a math class gave us a particularly interesting topic: an fishing fishing, fishing six no head, nine no tail, eight and a half, a total of How many fish to catch? Many students speak in unison on the spot to answer; 6 +9 +8, a total of 23 fish. The teacher shook his head and said: no, please classmates think again! Classroom silent, everyone is thinking positively. As I thought deeply, I wrote a note on the table with my finger, and fled to my heart, and immediately answered: “The fisherman did not fish any fish, and the number was” 0 ".
