1. The problem is to order whole numbers, which means arranging them from smallest to largest or vice versa. 2. Whole numbers are non-negative integers including zero: $0, 1, 2, 3, \ldots$ 3. To order whole numbers, compare their values directly since they are discrete and countable. 4. For example, given numbers $5, 2, 9, 0$, ordering from smallest to largest is $0 < 2 < 5 < 9$. 5. This ordering helps in understanding magnitude and is fundamental in arithmetic and number theory. 6. Always remember: smaller whole numbers come before larger ones when ordering ascendingly.
