- Natural numbers will Always be whole numbers.
Natural numbers are positive integers (whole numbers), so, they are always whole numbers.
- Integers will Sometimes be natural numbers.
Not all integers are natural numbers. Negative integers are not natural numbers while positive integers are natural numbers.
- Irrational numbers will Always be real numbers.
Real numbers consist of both irrational and rational numbers. So, all irrational numbers are real numbers.
