Definition
A compound inequality is two inequalities joined by AND or OR, describing values between or outside bounds.
Examples
- -2 < x <= 6 is a compound inequality.
- x < 0 or x > 5 is a compound inequality.
Key rule
AND gives a between-region; OR gives two separate regions.
Memory hook
Compound = two inequalities working as a pair.
