In "Interval Notation" we just write the beginning and ending numbers of the interval, and use: [ ] a square bracket when we want to include the end value, or. ( ) a round bracket when we don't.

Write interval notation using a beginning bracket or parenthesis and an ending bracket or parenthesis. Next, write the beginning number of the set followed by a comma and the ending number of the set. Brackets indicate that the set includes the beginning and/or ending number.

Interval notation is a way of writing subsets of the real number line . A closed interval is one that includes its endpoints: for example, the set { x | − 3 ≤ x ≤ 1 } . To write this interval in interval notation, we use closed brackets [ ]: [ − 3 , 1 ] An open interval is one that does not include its endpoints, for example, { x | − 3 < x < 1 } .

The easiest way to find interval notation is to first draw a graph on a number line as a visual representation of what's going on in the interval. If the endpoint of the interval isn't included in the solution (for < or >), the interval is called an open interval.
