Numbers Between 21 and 31
TOTAL NUMBERS: 9
The numbers between 21 and 31, excluding both endpoints, are listed below. Useful for math problems, ranges, and number sets.
What Are the Numbers Between 21 and 31?
To find the numbers between 21 and 31 excluding the bounds, we list all whole numbers greater than 21 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 21 and 31 in exclusive mode, the count is: 9.
