史上最全数学符号、公式的英文读法,干货满满
史上最全数学符号、公式的英文读法，干货满满说起英语和数学，大概每个人都有难忘的回忆。
可是学了十几、二十年的英语和数学，你会用英语来表达数学吗？烂熟于心的数学符号和表达式用英语会说吗？想不想挑战一下自己？先来一个最简单的：1+2=3 用英语怎么说？One plus two equals three. 哎呦不错哦，继续！尝试：½ (x + y)英语怎么说？这个呢？这个呢？就知道你说不出来咯～今天这篇文章，将从小学到博士后的数学符号和表达式的英文读法一网打尽，全都总结好了！惊不惊喜？意不意外？！这篇文章囊括了从小学数学到高等数学，涉及到的主要符号和表达式的英文读法，查阅了很多资料，确保英文100%准确，请放心使用。
数学是所有理工学科的基础，是认识科学世界基本工具，数学的重要性不言而喻。
所以，这篇文章是老少咸宜的、吐血总结的干货。
可以帮助：中小学生：了解英语不仅是“I am a student.My name is XXX.”,而是真正用于学习数学、学习知识的工具。
大学生:在外教的课堂上，在国际会议上，在外企里，面对常见的数学符号，简单的数学问题时，不可能在茶壶里煮饺子。
留学党:缩短刚到国外理解老师课堂讲课的过渡期。
学生家长可以为你家宝宝留着哦～基本数学符号1. 加减乘除"+"当作运算符加号时读作plus，比如：1+2 ➡️ one plus two当"+"放在数字前表示正数时，读作positive，比如：+4 ➡️ positive four同样，“-”也有minus和negative两种读法，分别是减号和负数。
"×" 两种读法都可以，国外的教授会常常读成times，可能因为比较简单吧，比如：9x6 ➡️ nine times six“÷”只有一种读法divided by，就是被…分成几份15÷3 ➡️ fifteen is divided by three注意：其中plus和minus是不用第三人称单数形式的，因为plus和minus根本就不是动词，而是介词。
