Senior one mathematics comprehensive formula problem
Xiaoming will return the book on Saturday.

Analyze the words in the title: the time to borrow books in the title is Wednesday, and reading from tomorrow means that the second day of borrowing books (Wednesday) is Thursday. Return the book two days after reading it, that is to say, the reading time is Thursday and Friday, and return the book two days later means returning it after reading it (Friday), that is, Saturday. According to the above analysis, it can also be solved by mathematical formula.

The mathematical expression of the topic is: 3+2+ 1=6.

3 is the start time, 2 is the reading time and 1 is the return time.

So return the book on Saturday.

Thoughts on solving application problems;

(1) Method of changing questions Some application questions are more complicated. When you answer them, you can appropriately change the expression of the known conditions in the question to make the quantitative relationship more obvious, so as to find a way to solve the problem. (For example, find the speed difference between two times)

(2) Inverse deduction can be used to think reversely about some application problems with specific structure, and take inverse operation from the final result, so as to explore the idea of solving problems. (for example, the application of a peasant woman selling eggs)
