数学用语的英文读法

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。

math 怎么读
“Math”是“mathematics”的缩写形式，发音为英式音标/mæθ/，美式音标/mæθ/。

在发音时，注意将舌头放在口腔的中央位置，清晰地发出“m”的音，接着发出“æθ”的音。

这个词汇的发音相对简单，重点在于保持声带的振动和舌头的正确位置。

“Math”作为“mathematics”的缩写，其含义与“maths”相同，都指的是数学这门学科。

数学是一门广泛应用的学科，涵盖了算术、几何、代数、概率等多个分支。

它不仅是科学研究的基础，也应用于工程、经济、金融、计算机科学等各个领域。

学习数学可以培养学生的逻辑思维、分析问题和解决问题的能力，为未来的学术和职业生涯打下坚实的基础。

除了作为“mathematics”的缩写外，“math”还可以作为“mathematical”的缩写形式，用于描述与数学相关的概念或术语。

在数学领域，“math”是一个普遍使用的术语，它代表了数学这门学科的精确性和普遍性。

总之，“math”作为“mathematics”的缩写形式，发音简单明了，含义广泛。

通过学习数学，我们可以深入了解数学的各个方面，培养自己的数学素养和解决问题的能力，为未来的学术和职业生涯做好准备。

大额数字的英文念法250000念成Two hundred and fifty thousand大额数字每三位一读，从小到大为：thousand, million, billion. 拿到一个数字，首先从个位开始数出位数，四位为thousand，七位为million，十位为billion。

心里有数了之后，读的时候要从大位开始。

比如：2，567，000首先知道这个数是7位，读的时候以2 million开始，后面每三位就按照平时读法，之后再加上thousand，就好了。

所以读成：two million five hundred and sixty-seven thousand.1,000 a/one thousand1,000,000 a/one million1,000,000,000 a/one billion (美a thousand million)我们中文是4位4位分（万、亿）英语是3位3位分（千、百万、十亿）习惯了就好了数学英文表达3 to the

常用英文数学式符号的读法Pronunciation of Numerals 数词的读法----------------------------------------------------------------------1.Cardinals and Ordinals 基数和序数(1)100以内的数词基数序数Roman ArabicNumerals Numerals[附注]拼写规则罗马数字共有7个，即I(1)，V(5)，X(10)，L(50)，C(100)，D(500)，M(1000)。

按照下述的规则可以表示任意正整数。

•重复数次：1个罗马数字重复几次，就表示这个数的几倍。

•右加左减：o在一个较大的罗马数字的右边记上一个较小的罗马数字，表示大数字加小数字。

o在一个较大的罗马数字的左边记上一个较小的罗马数字，表示大数字减小数字。

o但是，左减不能跨越一个位数。

比如，99不可以用IC表示，而是用XCIX表示。

（等同于阿拉伯数字每位数字分别表示）▪例如：999 = 900+90+9 = CM+XC+IX = CMXCIX o此外，左减数字不能超过1位，比如8写成VIII，而非IIX。

o同理，右加数字不能超过3位，比如14写成XIV，而非XIIII。

•加线乘千：在1个罗马数字的上方加上1条横线或者在右下方写M，表示将这个数乘以1000，即是原数的1000倍。

o同理，如果上方有2条横线，即是原数的1000000倍。

•例外：由于IV是古罗马神话主神朱庇特（IVPITER，古罗马字母没有J和U）的首字，因此有时用IIII代替IV。

(2)1000以上的数词1,000 = one thousand 一千10,000 = ten thousand 一万100,000 = one hundred thousand 十万1,000,000 = one million 一百万10,000,000 = ten million 一千万100,000,000=one hundred million 一亿(3)十亿以上的大数，英美有不同的读法：英国美国十亿 one thousand million = one billion百亿 ten thousand million = ten billion千亿 one hundred thousand million = one hundred billion万亿 one billion = one trillion2.Fractions 分数通常将分子读为基数，将分母读为序数。
