1. The problem is to arrange a set of numbers or expressions from the least to the greatest. 2. To do this, we first need the list of numbers or expressions to compare. 3. Once we have the list, we compare each pair to determine their order. 4. We use the rule that for any two numbers $a$ and $b$, if $a < b$, then $a$ comes before $b$ in the order. 5. After comparing all pairs, we arrange the numbers in ascending order. 6. Without a specific list, we cannot perform the ordering, so please provide the numbers or expressions to order.
