picture of a graduated straight line that serves as abstraction for real numbers; coordinate system in one-dimensional space
A number line is a straight line with equally spaced marks that represent numbers in order, serving as a visual way to show how real numbers relate to each other. It's a fundamental tool in mathematics that helps people understand concepts like distance, ordering, and basic operations with numbers.

The order of the natural numbers shown on the number line
A number line is a graphical representation of a straight line that serves as spatial representation of numbers, usually graduated like a ruler with a particular origin point representing the number zero and evenly spaced marks in either direction representing integers, imagined to extend infinitely. The association between numbers and points on the line links arithmetical operations on numbers to geometric relations between points, and provides a conceptual framework for learning mathematics.
