Interval notation is a method of writing down a set of numbers. An example of this is all numbers that are greater than five.Ê
The real numbers between 1 and 6 form an interval on the number line. This interval is denoted as (1, 6), where the parentheses indicate that the endpoints 1 and 6 are not included. In interval notation, this set can be written as {x | 1 < x < 6}. This set includes all real numbers greater than 1 and less than 6.

Numbers greater than 500,000 include any numerical value that is larger than 500,000 on the number line. This encompasses all integers from 500,001 to infinity, as well as any real numbers, fractions, or decimals greater than 500,000. In mathematical notation, this can be represented as {x | x > 500,000}, where x represents any number greater than 500,000.

It is (-3, 5].
(-3, 5] = {x : -3 < x ≤ 5}
Sets can be written in various ways, including roster notation, set-builder notation, and interval notation. Roster notation lists all the elements of a set, such as ( A = {1, 2, 3} ). Set-builder notation describes the properties of the elements, like ( B = { x \mid x > 0 } ). Interval notation is often used for sets of numbers, such as ( C = (0, 5] ), indicating all numbers greater than 0 and up to 5.
Numbers greater than 0.7 are any real numbers that are larger than 0.7 on the number line. This includes decimals such as 0.8, 0.9, 1.0, as well as fractions like 3/4, 7/8, and integers like 1, 2, 3, and so on. In interval notation, the set of numbers greater than 0.7 can be represented as (0.7, ∞), where the parentheses indicate that 0.7 is not included in the set and the infinity symbol represents all numbers greater than 0.7.
Interval notation uses the symbols [ and ( to indicate closed an open intervals. The symbols can be mixed so that an interval can be open on one side and close on the other. Given two real numbers, a, b we can have (a,b) which is the interval notation for all numbers between a and b not including either one. [a,b) all numbers between a and b including a, but not b. (a,b] all numbers between a and b including b, but not a. [a,b] all number between a and b including a and b.
There is more than one notation, but the open interval between a and b is often written (a,b) and the closed interval is written [a,b] where a and b are real numbers. Intervals may be half open or half closed as well such as [a,b) or (a,b]. For all real numbers, it is (-infinity,+infinity), bit use the infinity symbol instead (an 8 on its side).

The real numbers between 1 and 6 form an interval on the number line. This interval is denoted as (1, 6), where the parentheses indicate that the endpoints 1 and 6 are not included. In interval notation, this set can be written as {x | 1 < x < 6}. This set includes all real numbers greater than 1 and less than 6.
Interval Notation
The interval of 0 and 180 refers to the range of values between 0 and 180, inclusive. This interval can be represented in mathematical notation as [0, 180]. It includes all real numbers starting from 0 up to and including 180. This range is commonly used in various contexts, such as angles in geometry, where it represents a half-circle.
{x| x ≥ 6} or the interval [6,∞).
