My math teacher forces me to use this and I hate It! It says you can learn via interactive stories, but those are nowhere to be found and when you click on the "Learn" tab it just pushes you to buy the premium membership and doesn't actually have anything there. The games are horrible and make no sense, some are copies of each other. They also lie about being a popular site that everyone uses, when I have never heard of it in my life until my math teacher forced me to use it. Horrible for students, parents, and their kids, there are much better ways to learn math, such as Freckle. Stay away
