What is the first thing to learn about mathematics?

I am working hard to solve mathematical problems. A lot of questions. Various problems is even better! The harder the better

It is one way to deal with a series of past tests, preferably to improve it, preferably under simulated test conditions

At the heart of mathematics is to fully understand the variables and their interrelationships in equations and equations.

In most cases, you will have to spend a lot of time understanding and working on the proof.

In the lesson, pay attention to all the work examples displayed in the instructor, professor, or whiteboard textbook, apply the knowledge gained from it to the solution, cover only the various new problems taught by the instructor It is done. It is your own, given in the class or removed from your textbook

I forgot to mention important things, but you need to spend at least an hour a day to solve math problems.

No, this is a paradox. If you do not have a mathematical mind, one day or the next day, you will not be able to go ahead. The good thing is that you can learn mathematics. First, remove the following syndrome. "This is too difficult." In any case, data science is more difficult, so it's best to start with simple mathematics. I learned some thought calculus, some statistics, talked about, thinking about mathematics, and then returned. Some people want their small boxes to have a well-defined interface, what to put in, and what to expect. Again, the syndrome of a person who just just got a good can just cough on the spot. You must understand it. Sometimes you can define and improve it yourself, sometimes you have to accept that mess and play with it

"Mathematics", some people may think mathematics is difficult and abstract when you hear that word. The important thing in mathematics is simply about numbers and formulas. However, when people study mathematics thoroughly, there is another important thing called "proofreading". Proofreading in mathematics classes plays an important role in deepening students' understanding. Occasionally when students explain the official and explain how to use it to solve mathematical problems without proveing ​​how the formula is formed, usually students only remember the formula I do not understand the concept. Under these circumstances, students can easily forget teaching materials and formulas. Therefore, by demonstrating in the classroom of mathematics, it is important to improve students' understanding of the concept of teaching materials.
