The term "intriguer" doesn't have a standard definition in mathematics or common usage as it relates specifically to numbers. However, based on the options you've provided, it seems like there may be a misunderstanding or a mix-up with terminology.
If we look at the options given:
- A positive or negative whole number and zero - This describes integers.
- A number greater than zero - This describes positive numbers.
- A number less than zero - This describes negative numbers.
- A visual display of numbers and relation to each other - This describes charts, graphs, or diagrams (like a number line).
If you meant to refer to a specific mathematical concept or term, please clarify, and I'd be happy to help!
