The smallest whole number is 0. Whole numbers are defined as the set of non-negative integers that include zero and all positive integers. Therefore, the set of whole numbers can be represented as follows:
- 0
- 1
- 2
- 3
- 4
- 5
This sequence continues indefinitely, meaning that whole numbers extend infinitely towards positive values. It’s important to note that while many numbers are considered in various mathematical contexts, zero serves as the foundational element of the whole number system, representing the absence of quantity. In summary, when asked which whole number is the smallest, the clear and definitive answer is 0.
