Inequality & Interval Converter
Understanding Notations
This tool converts between inequality notation and interval notation.
Interval Notation
Uses parentheses `()` for exclusive endpoints (not included) and square brackets `[]` for inclusive endpoints (included).
`(` or `)` corresponds to `<` or `>`.
`[` or `]` corresponds to `≤` or `≥`.
Infinity `(∞)` is always exclusive.
Examples
Inequality: \(x > 5\)
Interval: \((5, \infty)\)
Inequality: \(-2 \le x < 3\)
Interval: \([-2, 3)\)
Inequality: \(x \le 0 \text{ or } x > 4\)
Interval: \((-\infty, 0] \cup (4, \infty)\)
