1. The first is inequality. If I remember correctly, the first one is inequality. I think this chapter is very important. Arithmetic calculation is mostly the transformation of inequality. The (most important) inequality solving problem, intersection problem ... (especially the root problem, we must master it well)

2. Then there is the function. Mainly some properties (domain and monotonicity) of common functions (exponential function, logarithmic function and inverse function).

3. If the first two blocks are well done, the order behind them is not important.

Key points:

The source of 1. formula theorem must be thoroughly understood.

2. All exercises after class must be returned.

In addition, you can do less when you understand the topic, and don't do more if you don't understand it.

4. Make corrections.
