在日常生活中我们经常会碰到各种数学运算,在跟外国客户谈生意时,往往会被问到一些专业计算方法,那么我们该如何用英语将数学运算表达出来呢?下面就常用的几种数学运算的英语表达进行讲解。

  1. 加减乘除的英文表达

    加法:用plus,and,add...to...或added to 等表示。如:3 2=5 Threeplus two is five.

    除法:用divided by,divid....into 等表示。如:20÷5=4 Twenty divided by five is four.

  2. 表示“几次乘方(幂)”时,指数用序数词,底数用基数词。当表示“平方”时用动词square,"立方”用动词cube.

    如:2的5次方,就是5个2相乘,2是底数,用基数词;5是指数,用序数词。the fifth power of two

    10的平方,就是ten squared.

    5的立方,英文是five cubed.

  3. 常用数学公式的表达法.

    a>b a is more than b.
