Inequalities

Inequalities compare values using <, >, ≤, or ≥.An inequality compares quantities instead of declaring them equal. It describes situations where values are greater than, less than, or within certain bounds, rather than exact matches. Working with inequalities requires extra care because not all algebraic steps behave the same way they do with equations. This section focuses on understanding how inequalities represent constraints and ranges of solutions, and why their solutions are often intervals rather than single values.
