# Find the number of whole numbers between the smallest and the greatest number of 2 digits.

**Given :**

The given numbers are smallest and the greatest number of 2 digits.

**To find :**

We have to find the number of whole numbers between the smallest and the greatest number of 2 digits.

**Solution :**

The greatest 2 digit number is 99.

The smallest 2 digit number is 10.

The number of whole numbers between the smallest and the greatest number of 2 digits including 10 and 99 $= 99-10+1 = 100-10 = 90$.

The number of whole numbers between the smallest and the greatest number of 2 digits excluding 10 and 99 is $90-2 = 88$.
