数学术语英文读法

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

常用英文数学式符号的读法
常用英文数学式符号的读法Pronunciation of Numerals 数词的读法----------------------------------------------------------------------1.Cardinals and Ordinals 基数和序数(1)100以内的数词基数序数Roman ArabicNumerals Numerals[附注]拼写规则罗马数字共有7个,即I(1),V(5),X(10),L(50),C(100),D(500),M(1000)。
按照下述的规则可以表示任意正整数。
•重复数次:1个罗马数字重复几次,就表示这个数的几倍。
•右加左减:o在一个较大的罗马数字的右边记上一个较小的罗马数字,表示大数字加小数字。
o在一个较大的罗马数字的左边记上一个较小的罗马数字,表示大数字减小数字。
o但是,左减不能跨越一个位数。
比如,99不可以用IC表示,而是用XCIX表示。
(等同于阿拉伯数字每位数字分别表示)▪例如:999 = 900+90+9 = CM+XC+IX = CMXCIX o此外,左减数字不能超过1位,比如8写成VIII,而非IIX。
o同理,右加数字不能超过3位,比如14写成XIV,而非XIIII。
•加线乘千:在1个罗马数字的上方加上1条横线或者在右下方写M,表示将这个数乘以1000,即是原数的1000倍。
o同理,如果上方有2条横线,即是原数的1000000倍。
•例外:由于IV是古罗马神话主神朱庇特(IVPITER,古罗马字母没有J和U)的首字,因此有时用IIII代替IV。
(2)1000以上的数词1,000 = one thousand 一千10,000 = ten thousand 一万100,000 = one hundred thousand 十万1,000,000 = one million 一百万10,000,000 = ten million 一千万100,000,000=one hundred million 一亿(3)十亿以上的大数,英美有不同的读法:英国美国十亿 one thousand million = one billion百亿 ten thousand million = ten billion千亿 one hundred thousand million = one hundred billion万亿 one billion = one trillion2.Fractions 分数通常将分子读为基数,将分母读为序数。
