This app is a fun way to improve your math skills. It will ask you if numbers and equations are equal or not, and you have to answer the question in a timely manner. This is a fun way to get better at math, and would be a great way to study for time tests in school. I used it for studying for the ACT, and honestly, my math score did improve! Even for those of you who no longer attend school and take tests, you should definitely try out this app. It's important to be on top of your brain game.
