Sure, I can provide you with 5 examples and questions related to ISBN-10, along with step-by-step explanations.

Example 1:
ISBN-10: 0-306-40615-2
Question: What is the check digit of the given ISBN-10?

Explanation:
To find the check digit, we need to perform a series of calculations.

Step 1: Multiply each digit by its position (from left to right), and sum up the results.
(0*1) + (3*2) + (0*3) + (6*4) + (4*5) + (0*6) + (6*7) + (1*8) + (5*9) + (2*10) = 127

Step 2: Divide the sum by 11 and find the remainder.
127 mod 11 = 3

Step 3: Subtract the remainder from 11.
11 - 3 = 8

Therefore, the check digit for the given ISBN-10 is 8.

Example 2:
ISBN-10: 3-598-21507-3
Question: Is the given ISBN-10 valid?

Explanation:
To determine the validity of an ISBN-10, we need to calculate the check digit.

Step 1: Multiply each digit by its position (from left to right), and sum up the results.
(3*1) + (5*2) + (9*3) + (8*4) + (2*5) + (1*6) + (5*7) + (0*8) + (7*9) + (3*10) = 249

Step 2: Divide the sum by 11 and find the remainder.
249 mod 11 = 4

Step 3: Subtract the remainder from 11.
11 - 4 = 7

Since the calculated check digit (7) matches the last digit of the ISBN-10, it is valid.

Example 3:
ISBN-10: 1-23-456789-X
Question: What is the value of 'X' in the given ISBN-10?

Explanation:
In an ISBN-10, 'X' represents the check digit. To find its value, we can follow the same steps as before.

Step 1: Multiply each digit by its position (from left to right), and sum up the results.
(1*1) + (2*2) + (3*3) + (4*4) + (5*5) + (6*6) + (7*7) + (8*8) + (9*9) + (X*10) = 285 + 10X

Step 2: Divide the sum by 11 and find the remainder.
(285 + 10X) mod 11 = 0

Step 3: Since the remainder is 0, we can conclude that 10X must be divisible by 11.
10X = 0
X = 0

Therefore, the value of 'X' in the given ISBN-10 is 0.

Example 4:
ISBN-10: 9-876-54321-0
Question: Is the given ISBN-10 valid?

Explanation:
Let's calculate the check digit to determine the validity of this ISBN-10.

Step 1: Multiply each digit by its position (from left to right), and sum up the results.
(9*1) + (8*2) + (7*3) + (6*4) + (5*5) + (4*6) + (3*7) + (2*8) + (1*9) + (0*10) = 285

Step 2: Divide the sum by 11 and find the remainder.
285 mod 11 = 1

Step 3: Subtract the remainder from 11.
11 - 1 = 10

Since the calculated check digit (10) matches the last digit of the ISBN-10 (0), it is not valid.

Example 5:
ISBN-10: 2-34-567890-9
Question: What is the sum of the digits in the given ISBN-10?

Explanation:
To find the sum of the digits in an ISBN-10, we can ignore the hyphens and add up all the remaining digits.

2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 0 + 9 = 53

Therefore, the sum of the digits in the given ISBN-10 is 53.

Example 2:
ISBN-10: 3-598-21507-3
Question: Is the given ISBN-10 valid?

Explanation:
To determine the validity of an ISBN-10, we need to calculate the check digit.

Step 1: Multiply each digit by its position (from left to right), and sum up the results.
(3*1) + (5*2) + (9*3) + (8*4) + (2*5) + (1*6) + (5*7) + (0*8) + (7*9) + (3*10) = 249

Step 2: Divide the sum by 11 and find the remainder.
249 mod 11 = 4

Step 3: Subtract the remainder from 11.
11 - 4 = 7

Since the calculated check digit (7) matches the last digit of the ISBN-10, it is valid.

Example 3:
ISBN-10: 1-23-456789-X
Question: What is the value of 'X' in the given ISBN-10?

Explanation:
In an ISBN-10, 'X' represents the check digit. To find its value, we can follow the same steps as before.

Step 1: Multiply each digit by its position (from left to right), and sum up the results.
(1*1) + (2*2) + (3*3) + (4*4) + (5*5) + (6*6) + (7*7) + (8*8) + (9*9) + (X*10) = 285 + 10X

Step 2: Divide the sum by 11 and find the remainder.
(285 + 10X) mod 11 = 0

Step 3: Since the remainder is 0, we can conclude that 10X must be divisible by 11.
10X = 0
X = 0

Therefore, the value of 'X' in the given ISBN-10 is 0.

Example 4:
ISBN-10: 9-876-54321-0
Question: Is the given ISBN-10 valid?

Explanation:
Let's calculate the check digit to determine the validity of this ISBN-10.

(9*1) + (8*2) + (7*3) + (6*4) + (5*5) + (4*6) + (3*7) + (2*8) + (1*9) + (0*10) = 285

Step 2: Divide the sum by 11 and find the remainder.
285 mod 11 = 1

Step 3: Subtract the remainder from 11.
11 - 1 = 10

Since the calculated check digit (10) matches the last digit of the ISBN-10 (0), it is not valid.

Certainly! Here are two more examples and questions related to ISBN-10:

Example 6:
ISBN-10: 0-7475-3269-9
Question: Is the given ISBN-10 valid?

Explanation:
To determine the validity of an ISBN-10, we need to calculate the check digit.

Step 1: Multiply each digit by its position (from left to right), and sum up the results.
(0*1) + (7*2) + (4*3) + (7*4) + (5*5) + (3*6) + (2*7) + (6*8) + (9*9) + (9*10) = 253

Step 2: Divide the sum by 11 and find the remainder.
253 mod 11 = 0

Step 3: Subtract the remainder from 11.
11 - 0 = 11

Since the calculated check digit (11) is not a valid digit (as it exceeds 9), the given ISBN-10 is not valid.

Example 7:
ISBN-10: 1-2345-6789-6
Question: What is the sum of the even-positioned digits in the given ISBN-10?

Explanation:
To find the sum of the even-positioned digits in an ISBN-10, we can ignore the hyphens and add up the digits at positions 2, 4, 6, 8, and 10.

2 + 4 + 6 + 8 + 6 = 26

Therefore, the sum of the even-positioned digits in the given ISBN-10 is 26.

I hope these examples and explanations help you understand ISBN-10 better. Let me know if there's anything else I can assist you with!
