Mathematics here stayed over again

I have made a few questions of the years, some questions are very simple.

But it is still a bit of hard work.

Discover a lot of questions or test foundations

Basic, must pay attention to, the previous learning is impetuous

Now we must stabilize the heart and make a foundation.

Say yourself: don't be a good high, step by step. . .

This is very important!
