Math Duel is a math race where 2 people sit on 2 sides of the iPad. First you pick a level from addition, subtraction, multiplication and division. You can also mix all of those together to practice them at the same time. After you do that, you can pick how big you want your numbers to be in the problems. You can pick how many numbers you want inside of the problem. The two people can be practicing different math at the same time. Every time you beat your opponent in a fact your bar will move up. When your opponent beats you, your bar will move back. To win the game,you have to answer the most math facts and get your bar to go to the end.
I give it 4 stars.
