The technical edition of this book has relatively little content and a small number of questions. Just talking about simple knowledge points and some examples. In the past, it was not edited by Mr. Chen Jian (in the past, it was edited by Mr. Jin Yuan), but this year it was edited by Mr. Chen Jian, which is the easiest one. Recommended for students with a math score below 80 in the college entrance examination. It should also be pointed out that this course is also taught by Chen Jian and Chen Jian. However, there are many contents in the Beijing Science Edition, which are recommended to students who are above 100 in the NMET. So everyone can make a choice according to the situation.

The above is the difference between the two versions. I hope it helps you.
