阿拉伯数字
在生活中,我们经常会用到0、1、2、3 、4、5、6、7、8、9这些
数字。那么你知道这些数字是谁发明的吗?
这些数字符号 原来是古代印度人发明的,后来传到阿拉伯,又从阿
拉伯传到欧洲,欧洲人误以为是阿拉伯人发明的,就 把它们叫做“阿
拉伯数字”,因为流传了许多年,人们叫得顺口,所以至今人们仍然
将错就错, 把这些古代印度人发明的数字符号叫做阿拉伯数字。
一、认识图形
现在,阿拉伯数字已成了全世界通用的数字符号。

数学小知识
运算顺序

一个算式中有小括号,运算顺序是先算小括号中的算式,如

(3 + 4)中,应先算括号中的3 + 4 得7,再算10 – 7 得10 -
3;

一个算式是连加、连减或加减混合,如果没有小括号,运算

顺序是“从左往右”,如10 – 3 + 4 中,应先算10 – 3 得7,
再算7 + 4 得11;
