学习了小数点以后,我觉得小数点太神奇了,一个小小的点,它的移动能让数变大或变小。我想考考我的老爸,看他知不知道小数点的奥秘。于是,我对爸爸发问:“小数点能使一个数变大或变小,非常神奇,爸爸你觉得呢?”爸爸笑眯眯地说:“我可不那样认为……”我急不可耐地打断爸爸的话:“如果你不信,那我就举几个例子。比如38,小数点往中间一站,38变成了3.8,缩小到原来的十分之一了。” After learning the decimal point, I think the decimal point is amazing, a small point, its movement can make the number larger or smaller. I want to test my father to see if he knows the secret of the decimal point. So, I asked Dad: “The decimal point can make a number larger or smaller, very magical, Dad you think?” “Dad smiled and said: ” I do not think so ... “I am impatient Break my father’s words: ”If you do not believe it, then I will give you a few examples, such as 38, the decimal point to the middle of a stop, 38 has become 3.8, reduced to the original one-tenth.
