put this solution on YOUR website! What is the minimum and maximum nuber of digits in the sum of any two four-digit numbers?
The minimum number is when we add the least two four
digit numbers
1000
+1000
-----
2000
That has four digits, so 4 is the minimum number of
digits it can have.
--------------------------------------
The maximum number is when we add the greatest two
four digit numbers
9999
+9999
-----
19998
That has five digits, so 5 is the maximum number of
digits it can have.
