This document provides instructions and examples for comparing and expanding numbers. It explains how to find the greatest and smallest number from a set using comparisons. It also shows how to arrange digits to make the greatest and smallest possible numbers. Finally, it demonstrates expanding numbers by place value, such as writing 2222 as 2*1000 + 2*100 + 2*10 + 2.
