数学运算符号的英文表达小数、分数、百分数和运算符号1. 小数表示法(1) 小数的读法小数点左边的数通常按基数词读，若为三位以上的数，也可按编码式读法读出，即将数字单个读出；小数点右边的数通常按编码式读法单个读出。
如：6.86 six point eight six14.15 fourteen point one five345.456 three four five point four five six或three hundred and forty－five point four five six(2) 小数中“0”的读法“0”在小数中通常读作nought（英）或zero（美），也可读作字母o。
如：0.08 （nought）point nought eight 或（zero）point zero eight9.07 nine point o seven2. 百分数表示法百分数中的百分号％读作percent。
如：6% 读作 six percent0.6% 读作（nought） point six percent500% 读作five hundred percent3. 倍数表示法倍数表示方法很多，如：This room is four times as big as mine. 这个房间是我房间的四倍。
This room is three times larger than that one. 这个房间比那个房间大两倍。
The output of coal has doubled. 煤的产量增加了一倍。
My aunt is as old again as I am. 我姑姑年龄比我大一倍。
Productivity is increased three fold. 生产效率提高了两倍。
The volume of the Sun is about 1,300,000 times that of the Earth.太阳的体积约为地球的1300000倍。
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。
那你就得了解各种数学名称了，比如“y分之x”是“x over y”，“x乘以y”是“x times y”，“除以”是“divided by”，加plus, 减minus；“x的y次方”是“x to the power of y”，“根”是“root”，几次跟就是几的英语序数形式，6次根=6th root。
1.(A的三次方+B的立方根-CXD的五次方)/E=F 读做:A cube plus the cube root ofB minusC multiplied by the 5th power of D, all divided by E equals F.2.(6+3+7/12-4.35X5)/(9*1/3) 读做: Six plus three and seven twelfths minus four decimal three five multiplied by fiv e, all divided by nine and a third.3. 基本术语：数学 mathematics 数字 number 双数 even number 单数 odd number 计算 calculate口算calculate mentally 笔算calculate using pen-and-paper 竖式vertical form 一位数1-digit number两位数2-digit number 文字题word problem 应用题story problem4、常用符号： ＋ plus、 － minus、 ＝ equal(s)、＞ is greater/more than、＜ is less than ( ) brackets5、加减法及各部分名称：加法 addition 加数 addend 和 sum 减法 subtraction被减数 minuend 减数 subtrahend 差 difference6、数位知识：数位表place value chart 个 Units/Ones 十 Tens 百 Hundreds7、图形名称：长方体 cuboid 正方体 cube 圆柱 cylinder球 sphere长方形 rectangle 正方形 square三角形 triangle 圆 circle边 side 角 angle 面 face专业英语中常用符号和数学表达式1．数的分类complex number 复数zero;

数学术语英文在我们学习数学的过程中，会遇到各种各样的术语。
而当我们需要与国际上的数学领域进行交流，或者阅读国外的数学资料时，了解这些数学术语的英文表述就变得非常重要。
首先，让我们从最基础的数字和运算开始。
“零”在英文中是“zero”，“一”是“one”，“二”是“two”，以此类推。
而常见的运算符号，“加”是“plus”或者“add”，对应的加法算式可以表述为“One plus two equals three”（一加二等于三）。
“减”是“minus”或者“subtract”，例如“Five minus three is two”（五减三等于二）。
“乘”可以用“multiply”或者“times”，像“Two times three equals six”（二乘三等于六）。
“除”则是“divide”，比如“Six divided by two is three”（六除以二等于三）。
接下来是几何图形方面的术语。
“三角形”是“triangle”，“正方形”是“square”，“长方形”是“rectangle”，“圆形”是“circle”，“椭圆形”是“oval”，“菱形”是“rhombus”。
在描述图形的性质时，“边长”是“side length”，“周长”是“perimeter”，“面积”是“area”。
再看看代数领域。
“未知数”通常用“unknown”或者“variable”表示。
“方程”是“equation”，例如线性方程“linear equation”。
“函数”是“function”，像常见的一次函数“linear function”，二次函数“quadratic function”。
“系数”是“coefficient”，“常数”是“constant”。
在统计学中，“平均数”是“average”或者“mean”，“中位数”是“median”，“众数”是“mode”。
“概率”是“probability”，“随机变量”是“random variable”。
数学符号和公式的英语读法如下：1.加号"+" 读作"plus"。
2.减号"-" 读作"minus"。
3.乘号"×" 读作"times"。
4.除号"÷" 读作"divided by"。

8.不等号"≠" 读作"not equal to"。
9.大于等于号"≥" 读作"greater than or equal to"。
10.小于等于号"≤" 读作"less than or equal to"。
11.约等于号"≈" 读作"approximately equals"。
12.百分号"%" 读作"percent"。
13.度数符号"°" 读作"degree"。
14.开方号"√" 读作"square root"。
15.正负号"±" 读作"plus or minus"。
16.正负平方根号"∛" 读作"cubed root"。
17.正负立方根号"∛" 读作"cubed root"。
