Question

How many whole numbers are less than n+1

Answer 1

`n`.

Explanation:

Assuming that
`n \in Z^(+)`, then all number less than
`n+1` are

`n+1-1=n`

Notice that the "plus one" indicates that the whole number shown by the expression
`n+1` indicates a whole number greater than
`n\\` by one unit. So, we just subtract one whole unit to achive a number less than the given expression.

Therefore, the answer is
`n`.
