Simply put, it is a big problem, which integrates a lot of mathematics knowledge you have learned. Maybe a question covers the key knowledge points of mathematics in a semester. Like application problems, you should have done it and applied some algebra knowledge you have learned. This is a comprehensive question.

In fact, there is no need to ask this question, because you will understand it naturally if you have more contact ~ We also distributed five sets of math comprehensive articles for our holiday homework at that time ~ Do more and you will understand ~ ~ ~

I hope it helps you.
