从前有一个村子，那里生活着不同的数字小朋友和加减先生。许多数字小朋友都喜欢找加先生那里去加自己，所以加先生很快乐，很幸福，而且加先生也很喜欢数字小朋友，如果加先生一看见数字小朋友就连忙跑过去加它们。许多数字小朋友都不喜欢到减先生那里去减自己所以减先生很孤独，所以减先生很讨厌数字小朋友，如果减先生一看见数字小朋友就冲上去减它们。一加就是加自己的一半，一减就是减自己的一半。
一次，12小朋友在回家的路上 遇到了正在生气的减先生，减先生一看到12小朋友就高兴了，说：“哈哈，终于有人出气了。”一下子，12小朋友就变成了6，从此，这个6小朋友就伤心。一次这个6小朋友在学校遇到了一个9，这个9小朋友很调皮，如果它犯了错，它就倒过来变成6让老师认不出来。它可以变成6或9来不认错，有时让这个6来承担自己所犯下的错误，一次它们和数字玩捉迷藏，它们俩倒来倒去，让其它数字分不清它们谁是6，谁是9。
到了秋天数字学校举办了运动会6和9都参加了，其中9跑的最快，眼看9就要到了中点，忽然9摔跤了落在后面的6走过来拉起了9一步一步的走向终点，就在这时，落在后面的运动员追了上来，超过了它们，9小朋友问6小朋友为什么不自己先跑，6小朋友说：“不能只顾自己，而丢下同伴不管。”
从此，6小朋友和9小朋友成了形影不离的好朋友。
