Math Problem Statement

Create an input that takes in a number.

Use the modulus to see what the remainder would be if you divide that number by 7.

Print the remainder.

For example:

Input: 10

Output: 3

Another example:

Input: 23

Output: 2

Solution

Here’s a Python program that takes a number as input, uses the modulus operator to find the remainder when divided by 7, and prints the remainder:

python
# Taking input and converting it to an integer number = int(input("Enter a number: ")) # Finding the remainder when divided by 7 remainder = number % 7 # Printing the remainder print(remainder)

Example Execution

If the user inputs:

  • 10, the remainder when divided by 7 is 3.
  • 23, the remainder when divided by 7 is 2.

Output:

For input 10:

3

For input 23:

2

Would you like to explore more or modify the code? Here are five related questions:

  1. What happens if the input is exactly divisible by 7, like 14 or 21?
  2. How can you modify the program to include a descriptive message, such as "The remainder is 3"?
  3. What is the modulus of a negative number when divided by 7?
  4. Can you modify the code to check divisibility by numbers other than 7?
  5. How would you modify the program to keep asking for input until the user enters a number divisible by 7?

Tip: The modulus operator (%) returns the remainder of the division, and it's useful for checking divisibility or determining leftover values.
