Inequalities
Inequalities show relationships between expressions that aren't necessarily equal. While equations use the = symbol, inequalities use comparison symbols like < (less than), > (greater than), ≤ (less than or equal to), and ≥ (greater than or equal to).
When solving inequalities, you can use the same basic operations as with equations—add, subtract, multiply, and divide on both sides. But here's a critical rule to remember: whenever you multiply or divide by a negative number, you must flip the inequality symbol. For example, when solving -3h > 15, dividing both sides by -3 gives you h < -5 (notice how > became <).
Graphing inequalities requires a number line and specific notation. Use an open circle for strict inequalities (< or >) to show the endpoint isn't included, and a filled circle for non-strict inequalities (≤ or ≥) to show the endpoint is included. Then draw an arrow pointing right for "greater than" expressions or left for "less than" expressions.
Remember: The direction of your arrow always follows the direction the inequality "opens" toward—right for greater than, left for less than!

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.
Samantha KlichAndroid user
Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
