数学运算符 的英文表达

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。

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

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。

数学术语英文

数学术语英文

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”。

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

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。

数学符号英语表达

数学符号英语表达

数学符号英语表达在数学领域中,数学符号是必不可少的,因为它们可以将复杂的数学概念简洁明了地表达出来。

对于学习数学的人来说,掌握一些数学符号的英语表达是非常必要的。

下面就来分步骤讲解一些常用的数学符号英语表达:第一步:基本算术符号(1) +:plus, add, positive(2) -:minus, subtract, negative(3) ×:times, multiplied by(4) ÷:divided by, over以上是常见的基本算术符号,在数学中被广泛使用。

当我们想要对数字进行加、减、乘、除运算时,需要使用这些符号。

第二步:括号符号(1) ():parentheses 或 brackets(2) []:square brackets 或 brackets(3) {}:curly brackets 或 braces括号符号是用来表示优先级的,比如在一个算式中使用括号可以使表达式更加准确。

第三步:比较符号(1) <:less than(2) >:greater than(3) =:equal to(4) ≤:less than or equal to(5) ≥:greater than or equal to比较符号是用来比较两个数或算式的大小关系的,它们也被广泛使用。

第四步:基本数学符号(1) π:pi(2) ∞:infinity(3) ∑:sigma(4) ∆:delta(5) ∫:integral这些数学符号都有特定的意义和用途,比如π用来表示圆周率,∞表示无穷大,∫是积分符号等等。

最后,需要提醒的是,在数学中使用符号时,需要注意它们的大小写和不同符号的应用场景,尤其是在学术写作中,要正确使用数学符号,避免出现错误。

总之,数学符号是数学的重要组成部分,学习数学符号的英语表达可以帮助我们更好地理解和应用数学知识,同时也能够使我们的学术写作更加规范和准确。
