Numbers Between 9 and 31
TOTAL NUMBERS: 21
The numbers between 9 and 31, excluding both endpoints, are listed below. Useful for math problems, ranges, and number sets.
What Are the Numbers Between 9 and 31?
To find the numbers between 9 and 31 excluding the bounds, we list all whole numbers greater than 9 and less than 31. This is a common operation in mathematics, programming, and data filtering.
How to Calculate the Count of Numbers Between
The formula to calculate how many whole numbers are between two integers is:
- Inclusive:
abs(B - A) + 1 - Exclusive:
abs(B - A) - 1
So for 9 and 31 in exclusive mode, the count is: 21.
