This question examines the application of integer subtraction, and the answer is as follows:
1, according to the meaning of the question, 30 storybooks given are interference information, and 96 books contain this storybook, so they are not involved in the calculation.
2. The number of books shipped-the number of books lent = the number of books left, so it can be seen that 96-4=92 (books), so there are 92 books left in the library.
3. Solution of the formula: 96-4=92 (Ben). A: Last week, * * * borrowed four books, and there are 92 books left in the library.

Calculation method of subtraction:
1, a number MINUS the sum of two numbers is equal to subtracting each addend in the sum from this number in turn.
2. A number minus the difference between two numbers is equal to this number minus the minuend in the difference first, and then minus it.
Subtract a number from the sum of several numbers. You can choose any addend to subtract this number and then add it to the rest of the addends.
4. If a number subtracts several numbers in succession, you can add all the subtractions first, and then subtract the sum of the subtractions from the minuend.
