Problem
Each of the digits 3, 5, 6, 7, and 8 is placed one to a box in the diagram. If the two digit number is subtracted from the three digit number, what is the smallest difference?
[Align three boxes to the right and two boxes below so it looks like a three digit number subtracting a two digit number.]
Solution
Make the 3-digit number as small as possible (356) and the 2-digit number as large as possible (87). The smallest difference is
