Frequently Asked Questions
Interval notation is a way to represent a set of real numbers using brackets and parentheses. For example, [a,b] includes all numbers between a and b, including a and b.
A parenthesis ( or ) means the endpoint is not included (open interval). A bracket [ or ] means the endpoint is included (closed interval).
Currently, this calculator handles finite intervals. For infinite intervals (using ∞), you would need a separate tool.
