# What is the minimum and maximum number of digits in the sum if we add any two 3 digit number

Given: Sum of any two $3-$digit number.

To do: To find the maximum and minimum number of digits in the sum if we add any two $3-$digit number.

Solution:

Greatest $3$ digit number$=999$

Sum of greatest $3-$digit number$= 999+999 = 1998$

Therefore, maximum number of digits$=4$

Smallest $3$ digits number$=100$

Sum of the smallest number$=100+100=200$

Therefore, minimum number of digits $= 3$

Thus, if we add any two $3-$digit number, then minimum and maximum number of digits in the sum are $4$ and $3$.
