The smallest whole number is ____.
0
Step 1: What are whole numbers?
Whole numbers are counting numbers with zero.
They are: \(0\), \(1\), \(2\), \(3\), \(4\), \(5\), …
Step 2: List the first few
Write the beginning part to see the order clearly:
\(0\), \(1\), \(2\), \(3\)
Step 3: Compare their sizes
\(0\) comes before \(1\).
\(1\) comes before \(2\).
So the number at the very start is \(0\).
Step 4: Conclusion
The smallest whole number is \(0\).
