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。

数字符号英语表达法

科技英语中公式、数字、符号的表达法（一）加、减、乘、除的表达法加、减、乘、除四则运算是日常生活中必不可少的运算法。

英语中，+ 读作plus，（作为正号，还读作pozitive），—读作minus，（作为负号，还读作negative），×读作times [taimz]或multiplied by，÷读作divided by，= 读作equals 或is equal to。

如：25+6-8×7 ÷3 读作twenty five plus six minus eight times （multiplied by）seven divided by three。

另外，>读作greater than，< 读作less than，≈读作approximately equals。

如：a>b 读作a is greater than b，b<a读作b is less than a，π≈3.14读作π is approximately equal to three point one four。

（二）分数的表达法分数在英语里叫fraction，一般由分子（numerator['nju:məreitə]）和分母（denominator [di'nɔmineitə]）组成。

在一般情况下，分子用基数词（cardinal['kɑ:dinl] number）表示，分母用序数词（ordinal['ɔ:dinl] number）表示。

如：1/3 读作one third，1/5 读作one fifth，1/7 读作one seventh，1/25 读作one twenty-fifth。

因为后面的序数词都被看作名词，因此，如果分子大于1，分母就用序数词的复数形式。

如：2/3 读作two thirds，4/5 读作four fifths，3/7 读作three sevenths，5/6 读作five sixths，9/10 读作nine tenths 等等。

英文加减乘除四种表达方式

英文加减乘除四种表达方式英文作为全球通用的语言，不仅仅是口语和书写，还包括数学计算。

在数学计算时，英文有自己独特的表达方式，主要是加减乘除四种基本运算的表达。

本文将介绍四种运算的英文表达方式。

一、加法（Addition）加法是数学中最基本的运算之一，通常在英文中用加法符号“+”表示。

如果要用英文来表达加法运算，我们可以使用一些常见的句型。

1. “A plus B equals C”：这是加法表达最基础的句子，其中A和B代表两个加数，C代表和。

例如：2 plus 2 equals 4.（2+2=4）2. “A added to B equals C”：这个句子也很常见，其中，add to表示“添加到”。

例如：5 added to 7 equals 12.（5+7=12）3. “A and B together equal C”：该句型中，together表示“在一起”，表示两个数相加的结果。

例如：9 and 8 together equal 17.（9+8=17）二、减法（Subtraction）减法是加法的相反操作，在英文中通常使用减法符号“-”来表示，同样也有一些常见的句式表达方式。

1. “A minus B equals C”：其中A和B代表被减数和减数，C代表差。

例如：6 minus 3 equals 3.（6-3=3）2. “B subtracted from A equals C”：其中，subtracted from表示“减去”，A代表被减数，B代表减数，C代表差。

例如：10 subtracted from 15 equals 5.（15-10=5）3. “A take away B equals C”：其中，take away 表示“拿走”，A代表被减数，B代表减数，C代表差。

例如：20 take away 15 equals 5.（20-15=5）三、乘法（Multiplication）乘法是将两个或更多的数相乘，通常使用乘法符号“×”来表示，在英文中有一些常见的句式表达方式。

最全面最标准的数学符号公式的英语读法大全

最全面最标准的数学符号公式的英语读法大全目前国内绝大部分的英语学习，仍然停留在日常交流和一些常识性知识的英语。

我们虽然受过高等教育，但是专业的、学术的英语学习仍然匮乏，我们的课本是中文的、老师用中文授课、我们的知识体系也是中文的。

所以在阅读原版教材、写英文论文、参加国际学术交流等很多时候，会遇到英语瓶颈。

真正能够应用英语来进行知识的学习，工作等，起码需要明白数学中的英语，希望这篇文章能给您带来帮助。

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。

但是乘和除，的的确确是动词，出现第三人称单数的形式。

2. 比较运算符比较运算符用来比较两个表达式的大小关系，比如：1+4>3 ➡️ one plus four is greater than three为什么用is？这里one plus four 是介词plus 连接两个名词，但是one plus four 作为一个整体当作主语，因此不用are，而是is4+5=9 ➡️ four plus five equals nine 或 four plus five is equal to nine 其他的类推，只要你认识数学符号，应该不难用英语说出来。
