数学英语专业加减乘除计算
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。
