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。

数学表达式的英语读法

数学表达式的英语读法

基础篇1.加减乘除"+"当作运算符加号时读作plus,比如:1+2? oneplustwo当"+"放在数字前表示正数时,读作positive,比如:+4? positivefour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,比如:9x6? ninetimes six“÷”只有一种读法dividedby ,就是被⋯分成几份,?15÷fifteen3is dividedbythree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。

您记住了吗?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 ? oneplusfourisgreaterthanthree 。

这里oneplusfour 是oneplusfour 作为一个整体当作主语,因此不用是介词plus连接两个名词,但are,而是is。

4+5=9 ? fourplusfiveequalsnine 或fourplusfiveisequaltonine 3.括号英语里小括号,中括号,大括号这三个词也是没有一点相似,分别是:parenthesis ,bracket,brace.左括号叫做left或open,右括号叫做right或closed.4.级数表示到中学数学了~这张表里的“a”是变量,而不是冠词“一个”的意思哦。

|a|是a的绝对值或绝对值a,英文读作absolutevalueofa, 非常好理解。

a'是什么?a撇就是与a相关又不想重复的时候会用一下,英语里读成aprime,同样有两撇adoubleprime,三撇atripleprime⋯但是注意了,如果a'表示时间分秒里的分,或者其他有具体意义的时候,就要按照具体的意义去读了。
