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。

整数和小数的英语读法 (1)年号的读法：1979←→nineteen seventy-nine or nineteen hundred(and) seventy-nine; (2)电话号码、的货币的读法：1023←→one o two three;1227←→one double two(or two two)seven;4.27←→four dollars(and)twenty-seven(cents); (3)小数点的读法：13.91←→thirteen decimal(point)nineone;0.23=nought demical two three; (4)算术式的读法： 2+3=5 Two plus three is(equals,isequalto)five. 5-3=2 Five minus three is equal to two. 3×2=6 Three times two is six.or Three by two are six. 9÷3=3 Nine divided bythreemakesthree. 1.整数和小数的读法 3.24可以读作three point twenty-four或three<BR>twenty-four。

在美国买东西都要含税, 所以价钱多半都带有小数点, 通常小数点可以说point，也可以直接省略。

另外比较正式的说法为three dollars andtwenty-four cents, 但是在一般日常生活中几乎是听不到这种读法，而是直接读为three twenty-four。

在美国开支票的机会很多,要注意的是，支票上小数的写和读与平时有所不同。

在支票上，金额不仅要用阿拉伯数字写出，而且还要用英语在金额栏的最左边写出。

其中整数部分的第一个字母要大写,小数部分则用xx/100 来表示, 并在最后加上only。

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
