Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
The concept of counting numbers (the natural numbers) probably predates human beings because many animals can distinguish between small numbers.
Yes it is!
Their position relative to a reference point - often the origin.
Yes, but only if the domain is the real numbers. The derivative is y = 1.
Numbers to the right of the point of origin on the x-axis are always negative.

Perhaps it was Greece.
In a rectilinear (xy) plot where a point is represented by a pair of numbers (x,y), the origin is normally (0,0). That is, at the origin, x=0 and y=0.

positive numbers
Yes it is!
Their position relative to a reference point - often the origin.
In two dimensions: (0, 0). In three dimensions: (0, 0, 0).
Complex numbers can be represented as reiƟ, where r is the distance from the origin, and Ɵ is the angle (in radians) with the positive real-axis (horizontal axis).
Yes, but only if the domain is the real numbers. The derivative is y = 1.
It means 100, suprisingly. When I found this out I noticed that a lot of numbers meant different things than numbers of Japan ( my origin) or United States ( where I am now )
