[AI-generated answer — Explain Bot]

To determine if a number is negative or positive, you need to know the sign of the number. And to determine if a number is real, you need to ensure it is not an imaginary number or a complex number.

In the case of a real number, the number line can be used as a reference. Any number to the left of zero on the number line is considered negative, while any number to the right of zero is considered positive.

To determine if a number is negative or positive, you can observe its sign. If a number is preceded by a negative sign (-), it is a negative number. For example, if the number is represented as -a, it is a negative real number.

In summary, a negative real number is a real number that is less than zero and is represented with a negative sign in front of it.
