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!
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 :)
You can't do algebra without working with variables, but variables can be confusing. If you've ever wondered what variables are, then this tutorial is for you!
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 :)
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 help make graphing the intersection of two inequalities a breeze! This tutorial shows you how to graph two inequalities on the same number line and then find the intersection. Take a look!
Number lines help make graphing the union of two inequalities a breeze! This tutorial shows you how to graph two inequalities on the same number line and then find the union. Check it out!
