英语加减乘除运算的表示方法

英语口语加减乘除怎么说英语口语加减乘除怎么说英语口语:加减乘除怎么说?英语中的加减乘除，你可以说道么？先说一下“=”在英语里怎么说，“=”通常用is或equals或makes去则表示“+”号在英语里一般用这三个：①and②plus③add1.sevenand/pluseightmakesfifteen.7提8等同于15。

2.ifyouaddtentoeight,yougeteighteen.10提8等同于18。

“—”号在英语里一般用这三个：①minus②from③take(away)(from)1.eightminusfiveis(leaves)three.8减至5等同于3。

/8减至5余3。

（注：在减法里，“=”也可以用leaves,同汉语里的“余”） 2.4from20leaves16.20减4余16。

3.tentakeawayfourissix.10减去4得6。

“x”号在英语里通常用这两个：①times②multipliedby1.fivetimesthreeis/equalsfifteen.5乘以3等于15。

2.fivemultipliedbytwoequalsten. 5乘以2等于10。

“÷”号在英语里通常用这两个：①dividedby②into1.twelvedividedbyfourmakesthree. 12除以4等于3。

2.fourintotwelveisthree.12除以4等于3。

用英语定义+-×÷，你学会了没有？。

数学英语专业加减乘除计算英语口语中的数学跟书面上的数学语言有很大差别。

没有经历过英文环境下的小学和中学教育，可能一开始上纯英文授课的数学课或是其它的专业课，很多的数学符号、表达式、公式从老师的嘴里说出来都听不懂。

虽然拿着专业课本我们能看懂里面的公式、符号，因为毕竟数学也算是一门语言，但是我们却开口讲不出来怎样描述这些数学符号和公式。

中文名称：加法相关符号：+举例： 1 + 2 = 3 augend + addend = sum相关词汇：addition 加法、plus sign 加号、plus symbol 加号、augend 被加数、addend 加数、sum 和口语表达： One plus two equals three. 一加二等于三。

One is the augend, two is the addend, and three isthe sum. 1是被加数，2是加数，3是和。

The sum of one and two is three. 1与2的和是3。

If you add one and two, you get three. 1加上2，得到3。

We are doing an addition (operation). 我们在做加法（运算）。

中文名称：减法相关符号：-举例： 8 - 6 = 2 minuend -subtrahend = difference相关词汇：subtraction 减法、minus sign 减号、minus symbol 减号、minuend 被减数、subtrahend 减数、difference 差口语表达： Eight minus six equals two. 8减去6等于2。

8 is the minuend, 6 is the subtrahend, and 2 isthe difference. 8是被减数，6是减数，2是差。

8, subtract/deduct 6 gives you 2. 8减去6，得到2。

首先，请大家熟悉几个单词（不需要“背”，只要认识、会读就行）：1、addition[E5diFEn]n.增加, 附加物【数】加法（add+ition）add[Ad]vt.增加, 添加-ition, -ation, -ion等常作名词后缀2、subtraction[sEb5trAkFEn]n.减去[少], 扣除(from);【数】减法（subtract+ion）subtract[sEb5trAkt]v.(～from)减去, 减(sub+tract)sub-表示“下，在下；低于，次于，副；亚，次”之义tract= trahere [拿走](tr+act)3、multiplication[7mQltipli5keiFEn]n.[数]乘法, 增加, (动, 植的)繁殖, 增殖(multiplicat(e)+ion)multiplicate[5mQltipli7keit]adj.多种的, 多样的(multip(y)i+ate)multiply[5mQltiplai]vt., vi增殖; 繁殖, 增加; 做乘法;【数】乘(multi+ply)multi-[5mQltI][构] 表示“多，多种，多个”之义-ply表“折”4、division[di5viVEn]n.分开, 分割, 区分, 除法（divid(e)+sion）divide[di5vaid]v.分, 划分, 分开, 隔开di- = dis- “分离”请注意：公式中的加减乘除用的并不是这几个单词，这里只是希望大家能认识这几个单词，说不定以后遇到英文版的资料时就能大概地读懂了。

一、加法1 plus 1 equals 2. 1加1等于2.Two plus two is four. 2加2等于4。

pl u s[pl Q s]prep.加上adj.正的, 加的equal[5i:kwEl]adj.相等的, 均等的, 胜任的, 平静的, 合适的, 不相上下的n.相等的事物(或数量), 对手, 匹敌, 同辈vt.等于, 比得上注意：英语中q基本上都是和u组合在一起使用，请复习一下quit, quick, queen, question。

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;

复数的加减乘除运算复数在数学中是一种重要的概念，它由实数和虚数部分组成。

复数的加减乘除运算是我们在数学学习中经常遇到的问题。

本文将详细介绍复数的加减乘除运算方法和规则。

一、复数的表示形式复数通常可以表示为 a + bi 的形式，其中 a 为实数部分，bi 为虚数部分，i 为虚数单位，满足 i² = -1。

在这种表示形式下，a 和 b 分别称为复数的实部和虚部。

二、复数的加法运算复数的加法运算遵循实部相加，虚部相加的原则。

具体计算公式如下：(a + bi) + (c + di) = (a + c) + (b + d)i例如，计算 (2 + 3i) + (4 + 5i)，按照上述原则进行计算，得到结果为6 + 8i。

三、复数的减法运算复数的减法运算同样遵循实部相减，虚部相减的原则。

具体计算公式如下：(a + bi) - (c + di) = (a - c) + (b - d)i例如，计算 (5 + 6i) - (2 + 3i)，按照上述原则进行计算，得到结果为3 + 3i。

四、复数的乘法运算复数的乘法运算通过展开计算实现。

具体计算公式如下：(a + bi) * (c + di) = (ac - bd) + (ad + bc)i例如，计算 (2 + 3i) * (4 + 5i)，按照上述公式进行计算，得到结果为-7 + 22i。

五、复数的除法运算复数的除法运算需要借助共轭复数。

共轭复数的定义为：如果 z = a + bi，则其共轭复数为z = a - bi。

复数除法的计算公式如下：(a + bi) / (c + di) = [(ac + bd) + (bc - ad)i] / (c² + d²)例如，计算 (8 + 6i) / (2 + 3i)，按照上述公式进行计算，得到结果为2 + 1i。

综上所述，复数的加减乘除运算都有相应的计算规则和公式，我们可以根据这些规则和公式进行运算。
