Interval notation is a method used to express a range of numbers between two specific points. This method employs brackets and parentheses to signify if the endpoints are incorporated or excluded. The square brackets [ ] mean the endpoint is included, whereas parentheses ( ) indicate it's excluded. For example, the range [3, 8) includes 3 but does not include 8.
