我是“小小推销员”。今天，我来推销一种文具——计算器
I'm a "little salesman.". Today, I'm going to sell a kind of stationery -- calculator
计算器具有处理速度快、计算精度高、存储容量大、可靠性高、工作全自动以及使用范围广等通用性的特点。
The calculator has the characteristics of high processing speed, high calculation accuracy, large storage capacity, high reliability, fully automatic operation and wide range of use.
我这计算器是选用优质的塑料、电子元件，精心制作而成，颜色为深蓝色。它还可以进行数学计算，还拥有集成电路芯片。这个计算器采用滑盖设计，这一切都可以增加计算器的使用寿命，最适合我们学生用了，它的规格是：16cm×7.5cm，他的最少起批量为一件衣上。
My calculator is made of high-quality plastic and electronic components. The color is dark blue. It can also perform mathematical calculations and has integrated circuit chips. This calculator is designed with a sliding cover, all of which can increase the service life of the calculator, which is most suitable for our students. Its specification is: 16cm × 7.5cm, and its minimum batch size is one garment.
我这个计算器由50个按键、资格自然书写显示屏、一个滑盖组成。
My calculator consists of 50 keys, a natural writing screen and a slide cover.
我这个计算器不光有加、减、乘、除的功能，还可以计算根号，计算““π”。
My calculator not only has the functions of addition, subtraction, multiplication and division, but also can calculate the root sign and "π".
在使用的过程中，我们也要注意，首先，不要进水，在使用计算器之前，要把滑盖“滑”下来，套在背面，这样用起来就方便多了。
In the process of using, we should also pay attention to, first of all, do not water, before using the calculator, we should "slide" the sliding cover down and cover it on the back, so it is more convenient to use.
这个学生计算器，我希望大家多多用！
This student calculator, I hope you can use it more!
