interval
Also known as real interval, range, real range, interval of reals, interval of real numbers, interval of the real line
subset an ordered set that consists of all elements between two given endpoints
AI overview
An interval is a continuous segment of an ordered set, like all the numbers between two points on a number line. Intervals matter because they provide a simple way to describe and work with ranges of values in mathematics, statistics, and many real-world applications.

The addition x + a on the number line. All numbers greater than x and less than x + a fall within that open interval. Numeric intervals on the positive and negative sides of the number line.
In mathematics, a real interval is the set of all real numbers lying between two fixed endpoints with no "gaps". Each endpoint is either a real number or positive or negative infinity, indicating the interval extends without a bound. A real interval can contain neither endpoint, either endpoint, or both endpoints, excluding any endpoint which is infinite.
