Question

natural numbers are whole numbers
always
sometimes
never

Answer 1

Natural numbers are a set of positive whole numbers starting from 1 and going upwards (1, 2, 3, ...), and in some definitions, they may also include 0 (0, 1, 2, 3, ...).

So, to answer your question:

- **Always**: If you consider natural numbers as starting from 1 (excluding 0).
- **Sometimes**: If you include 0 in the definition of natural numbers.
- **Never**: If you consider only positive integers, then whole numbers would not apply.

The most common definition is that natural numbers are always whole numbers.
