Reader comments
This exercise book is rich in content and the questions are very targeted. I especially like the explanations of examples in it. They are clear and easy to understand, and I learned a lot of problem-solving skills. Just like the sentence in the book, "Mathematics is the key to the door of science." Through studying this book, I feel that I am one step closer to the door of science.
