Every whole number has its predecessor.
Step 1: Know the set of whole numbers.
Whole numbers are: \(0, 1, 2, 3, \ldots\)
Step 2: Understand the word “predecessor”.
The predecessor of a number means: one less than the number.
For a number \(n\), predecessor \(= n - 1\).
Step 3: Check this rule for \(0\).
Predecessor of \(0\) would be:
\(0 - 1 = -1\)
Step 4: Is \(-1\) a whole number?
No. Whole numbers do not include negative numbers.
Conclusion:
\(0\) does not have a predecessor in whole numbers.
So the statement “Every whole number has its predecessor” is false.
