Algebra 1 · Inequalities
Definition
OR (union) is a compound inequality true wherever either of the two inequalities is satisfied.
Examples
- x < 1 OR x > 5 covers both ends.
- x <= -2 OR x >= 3 covers the outside.
Key rule
The solution includes every value that satisfies at least one part.
Memory hook
OR = either one counts; both regions are in.
