Solve linear inequalities step-by-step and plot them on a number line (●/○) — including the negative division rule!
About this app
An interactive mathematics app designed to help students master linear inequalities and visualize their solution sets on a number line. It features an exploratory sandbox for inequalities, a step-by-step solver that demonstrates algebraic operations like subtracting constants and dividing by coefficients, and an interactive quiz to test understanding. Through visual feedback, users can easily grasp how multiplying or dividing by negative numbers flips the inequality sign and how filled or empty endpoints represent inclusive or exclusive boundaries.
Use cases
- Middle school or secondary students practicing algebraic inequalities and their corresponding graphical representation on number lines.
- Math teachers seeking a visual aid to explain inequality properties, inclusive versus exclusive boundaries, and the negative coefficient sign-flip rule.
- Self-learners looking for step-by-step guidance on solving linear equations and inequalities.
Features
- Interactive number line visualization with live adjustments for boundaries, inequality directions, and inclusive or exclusive endpoints using filled and empty circles.
- Step-by-step inequality solver that displays the visual and algebraic impact of subtracting constants and dividing by coefficients on both sides.
- Automatic sign-flip warnings and visual feedback when dividing by a negative number.
- Interactive quiz module where users solve randomly generated linear inequalities and input their corresponding boundary and direction to maintain a streak.
