There are exactly 89 two-digit numbers between 10 and 100.
The reference states that there are 90 distinct numbers between 10 and 100. However, based on how I have interpreted the question, 10 and 100 should be excluded, but 10 and 99 should be included. Therefore, I have deduced that the number between 10 and 100 would be 89.
- Two-digit numbers start from 10.
- The question asked about numbers between 10 and 100, meaning it should include everything from 11 up to and including 99.
- Therefore, 99 - 10 = 89 numbers
Alternatively, if you include 10 and exclude 100.
- Two digit numbers start from 10.
- The question asked about numbers between 10 and 100, meaning it should include everything from 10 up to and including 99.
- Therefore, 99 - 10 + 1 = 90 numbers.
