Is 0 a positive number or a negative number?
Okay, that makes sense. Can you explain why -1 is considered a negative number, but -i is not considered a negative imaginary number?
Certainly. The concept of a "negative number" refers to numbers that are smaller than zero, while the concept of "imaginary numbers" refers to the square roots of negative numbers. Although -1 is considered negative because it is smaller than zero, -i is not considered negative or positive as it is not a real number on the number line. Instead, it exists only in the imaginary plane.
