Sure! I can provide you with examples and questions related to ISBN-10, as well as step-by-step explanations on how to solve them.

What is an ISBN-10?
ISBN-10 stands for International Standard Book Number, which is a unique identifier for books. It consists of 10 digits, including numbers from 0 to 9 and one final check digit.

Example of an ISBN-10:
Let's take an example ISBN-10: 0-306-40615-2. The last digit, 2, is the check digit.

Steps to calculate the check digit:
1. Multiply each digit in the ISBN by its position, starting from the leftmost digit and moving to the right.
In our example: 0*10 + 3*9 + 0*8 + 6*7 + 4*6 + 0*5 + 6*4 + 1*3 + 5*2 = 112

2. Add up the results from step 1.
In our example: 112

3. Take the sum from step 2 and divide it by 11.
In our example: 112 / 11 = 10 (remainder 2)

4. Subtract the remainder from 11 to get the check digit.
In our example: 11 - 2 = 9

So, in the given example, the correct check digit is 9.

Problem Solving:
Now, let's solve a problem related to ISBN-10:

Question: Find the missing digit in the following ISBN-10 code: 1-56789-126-?

To find the missing digit, we need to calculate the check digit using the given code and determine the value that makes the calculation valid.

Steps to solve the problem:
1. Multiply each digit in the ISBN by its position, starting from the leftmost digit and moving to the right.
In this case, we have: 1*10 + 5*9 + 6*8 + 7*7 + 8*6 + 9*5 + 1*4 + 2*3 + 6*2 = ?

2. Add up the results from step 1.
In this case, we have: ?

3. Take the sum from step 2 and divide it by 11.
In this case, we have: ? / 11 = (some number)

4. Subtract the remainder from 11 to get the missing digit.
In this case, we have: 11 - (some number) = (missing digit)

By following these steps, you can calculate the missing digit in the given ISBN-10 code.

I hope this explanation helps! Let me know if you have any further questions.
