Today we're going to talk about some basic math vocabulary. This vocabulary is very simple but can come in handy if you're going to study abroad or if you just want to learn more English.

　　今日咱们将谈论一些根柢的数学词汇。这个词汇非常简略，可是假定你要出国留学或许你想学更多的英语，它可以派上大用场。

　　The first set of words were going to talk about are operations.

　　咱们要讲的第一组词是operations运算。

　　The most common operations are addition, subtraction,

　　multiplication and division, and those are what we'll talk about today.

　　最多见的运算是加、减、乘、除，这些就是咱们今日要谈论的。

　　

　　Addition is when you add two numbers together. This is called a plus sign. So for example, 4 plus 5 equals 9 or if I have 4 and add 5 I get 9.

　　加法就是两个数相加。这叫做加号。例如，4 + 5=9，或许说我有4，再加5，得到9。

　　

　　Subtraction is when you subtract one number from another number. This is called a minus sign. So for example 6 minus 4 equals 2 or if I have 6 and take away 4 I get 2.

　　减法就是用一个数减去另一个数。这叫做减号。例如，6 - 4=2，假定我有6，拿走4，得到2。

　　

　　Multiplication is when you multiply one number by another number. For example 4 times 3 equals 12 or

　　if I multiply 4 by 3 I get 12.

　　乘法就是用一个数乘以另一个数。例如，4乘以3等于12，或许4乘以3得到12。

　　

　　Division is when you divide one number by another

　　number. For example 12 divided by 2 equals 6 or if I divide 12 by 2 I get 6.

　　除法就是用一个数除以另一个数。例如，12除以2等于6，或许12除以2得到6。

　　Hopefully this has helped you it's very basic English but teachers don't talk about this vocabulary very often. Thank you for watching.

　　期望这对你有协助，这对错常基础的英语，可是教师不会常常谈论这个词汇，谢谢。

　　今日的内容都学会了么?

　　等待谈论交流心得~
