What Interval Notation Calculator does
This tool converts between inequality notation and interval notation, supporting both directions of conversion. Users input an inequality or interval and receive the equivalent representation instantly, which simplifies algebraic expressions and equations. The calculator handles various interval types, including bounded intervals, unbounded intervals, and special cases like the set of all real numbers, making it useful for students, teachers, and anyone working with algebraic expressions. It also provides explanations of interval notation concepts and symbols for those needing a refresher.

Best for
Students, teachers, and mathematicians who need to convert between inequality and interval notation for algebra assignments or to simplify expressions and equations.
Limitations
- Conversion types are limited to standard inequality and interval formats
- Results may not cover all complex or unusual interval cases beyond standard real number subsets
- The tool focuses on real line intervals and may not handle complex number sets or multi-dimensional spaces
Interval Notation Calculator FAQ
- Can this calculator convert any inequality into interval notation?
- Yes, the tool converts inequalities involving standard real number bounds into their interval notation equivalents, including bounded intervals, unbounded intervals, and special cases like all real numbers.
- What do the bracket symbols [ and ( mean in interval notation?
- Square brackets [ or ] indicate that the endpoint is included in the interval (inequality with ≤ or ≥), while parentheses ( or ) indicate the endpoint is excluded (inequality with < or >).
- How do I represent the set of all real numbers in interval notation?
- The set of all real numbers is represented as (-∞, ∞) in interval notation, where negative infinity and positive infinity are always expressed with parentheses since they are not actual numbers that can be included.
- Does the calculator explain the steps of conversion?
- Yes, the tool provides explanations of interval notation concepts and symbols, and includes a section describing how to write sets in interval notation, including the meaning of bracket symbols and infimum notation.
