Trying to figure out if the values in a replacement set are part of the solution set to an inequality? Learn how to find the answer to that question with this tutorial!
This tutorial will help you understand what a set is, and the different kinds of sets that you may see when you're working on algebra problems :)
Inequalities come up all the time when you're working algebra problems. In this tutorial you'll learn what an inequality is, and you'll see all the common inequality symbols that you're likely to see :)
Comparing fractions with unlike denominators? Don't want to find a common denominator? You don't have to if you take the cross product! Learn how to do this and make the comparison in this tutorial.
Venn Diagrams are really great tools for visualizing sets, especially when it comes to how sets intersect and come together. Check out this tutorial and see what we mean!
If you have ever stared at a number line with dots on it and wondered 'How could I summarize these dots?', then this is the tutorial for you!
Number lines are great ways to represent a group of numbers, and in this tutorial you'll see how to graph a group of numbers on a number line
Number lines are really useful in visualizing an inequality or a set. In this tutorial, you'll see how to graph both. Take a look!
Writing inequalities from a graph on a number line isn't so bad if you know what to do. Watch this tutorial to learn how!
Got an inequality in a word problem? This tutorial will show you how to define variables, translate a word problem into an inequality, and understand what it all means!
Venn Diagrams are a convenient way to figure out the union and intersection of sets. Use this tutorial to get some practice with union, intersection, and Venn Diagrams.

Need some extra practice converting solution phrases into set builder notation? This tutorial was made for you! Follow along as this tutorial shows you how to dissect each phrase and turn it into a solution in set builder notation.
Knowing the definition for a compound inequality is one thing, but being able to identify one in a word problem or phrase can be an entirely different challenge. Arm yourself by learning some of the common phrases used to describe a compound inequality and an absolute value inequality.
If you're not sure if a value is a solution to an inequality, you an always plug it in and see. This tutorial shows you how to determine if a value is a solution to an inequality.
Ordering numbers from least to greatest? Are the numbers in different forms? To make comparing easier, convert all the numbers to decimals. Then, plot those decimals on a number line and compare them! This tutorial shows you how!
