Visualize one-variable inequalities on an interactive number line.
Last updated: June 2026 | By Patchworkr Team
Strict inequalities exclude the endpoint. Inclusive inequalities include it.
Use >, >=, <, <=, ==, or != to explore different solution sets.
Solve x <= -1.
1. Choose <=
2. Enter -1
3. Highlight values at or below -1
Solution set: all integers from -10 to -1 in this view
What does a filled circle mean?
It means the endpoint is included.
What does a hollow circle mean?
It means the endpoint is excluded.
Can I use decimals?
Yes. The line still highlights integer values around the target.
What does != do?
It highlights every value except the one entered.
