同学们,我们都知道,在一个非0自然数的后面添上0,这个数的大小就变了。所以,0在数字十兄弟中昂首挺胸,骄傲极了!是啊,0往非0自然数后面一站,这个数就要因为0的到来而扩大。站一个0,原数就扩大10倍:站两个0,原数就扩大100倍;站三个0,原数就扩大1000倍……0,真是了不起。而现在我们学习了小数的性质:小数的末尾添0或者去掉0,小数的大小不变。从此,0就没有那么神气了。因为小数末尾的0有没有都不会改变小数的大小。例如0.6=0.60=0.600=0.6000
Classmates, we all know that adding 0 after a non-zero natural number changes the size of the number. Therefore, 0 is proud of being among the top ten brothers in the digital world. Yes, 0 is a stop behind non-zero natural numbers, and this number should be expanded by the arrival of zero. Station a 0, the original number to expand 10 times: two stations 0, the original number to expand 100 times; station three 0, the original number to expand 1000 times ... ... 0, really great. And now we learn the nature of the decimal: add 0 or 0 at the end of the decimal, the size of the decimal does not change. Since then, 0 is not so upset. Because zero at the end of the decimal does not change the size of the decimal. For example 0.6 = 0.60 = 0.600 = 0.6000
