All integers are whole numbers.
Step 1: Recall the sets.
\( \ldots, -3, -2, -1, 0, 1, 2, 3, \ldots \)
\( 0, 1, 2, 3, 4, \ldots \)
Step 2: Compare.
Whole numbers do not include negative numbers.
Step 3: Give a counterexample.
\( -1 \) is an integer.
But \( -1 \) is not a whole number.
Conclusion.
Since at least one integer (e.g., \( -1 \)) is not a whole number, the statement is false.
