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 by7
is3
.23
, the remainder when divided by7
is2
.
Output:
For input 10
:
3
For input 23
:
2
Would you like to explore more or modify the code? Here are five related questions:
- What happens if the input is exactly divisible by 7, like 14 or 21?
- How can you modify the program to include a descriptive message, such as "The remainder is 3"?
- What is the modulus of a negative number when divided by 7?
- Can you modify the code to check divisibility by numbers other than 7?
- 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.
