Understanding Interval and Inequality Notations
Interval and inequality notations are ways to represent sets of numbers. Intervals use brackets and parentheses to denote ranges, e.g., [a, b] includes numbers from a to b, while (a, b) excludes a and b. Inequalities use symbols like <, >, ≤, ≥ to define number ranges, for example, a ≤ x ≤ b. This tool helps convert between these notations for better understanding of mathematical ranges.
