原标题：“加，减，乘，除”的英语都不会？英语和数学老师在盯着你

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.

今天我们将讨论一些基本的数学词汇。这个词汇非常简单，但是如果你要出国留学或者你想学更多的英语，它可以派上大用场。

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

我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.

最常见的运算是加、减、乘、除，这些就是我们今天要讨论的。

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，或者说我有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，如果我有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，或者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，或者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.

希望这对你有帮助，这是非常基础的英语，但是老师不会经常谈论这个词汇，谢谢。
