You can use it to do simple calculations. In fact, in mechanical manufacturing, in the production site, in most cases, only the simplest elementary mathematics is used, and all the contents are added together, that is, the basic four operations of addition, subtraction, multiplication and division (none of which I will go back to primary school), and the application of simple trigonometric functions (sine cosine function, positive cotangent function and inverse trigonometric function) only needs to understand the definition. As for the transformation of trigonometric functions, solving trigonometric function equations and the like, then, simple rectangular, square, triangular, trapezoidal, circular and other areas, as well as volume calculation and weight calculation (and sometimes material cost calculation) of general simple geometric bodies. If you can't meet this standard, I suggest you really make up math. Otherwise, it will be difficult for you to become an excellent worker, which will greatly limit your development space.

Anyway, the operators in the production site are basically the basic knowledge of primary school mathematics except simple trigonometric functions. You don't need skills, you don't need to solve any problems, you just need to know the most basic application, that is, understand the definition. However, it is better to suggest a slightly stronger mathematical foundation. After all, just because you don't need it today doesn't mean you won't need it tomorrow. The stronger the ability, the better. Like some small factories with miscellaneous hairs, there are only a few people. A small technician not only needs to engage in production technology, but also sometimes drives ducks to the shelves to engage in design. At this time, you can use a lot of mathematical knowledge.
