8 of 25Well thought out and easy to use app. Excellent resources to learn how to quickly solve apparently lengthy math problems. A must have any preparing for GRE, GMAT, LSAT and other graduate school placement exams.
Keeps my mind sharp. Great app.
Lots of fun techniques to make mental arithmetic a bit easier. Would love to see more tricks added in the future.
The 10’s complement practice problems are wrong while the lessons are correct. This is a huge bummer because learning complements are essential for certain types a large addition/ subtraction
One ask: I wish the "play" selected categories were persistent. I.e. The ones you selected the last time you played are selected them next time you played. Update: Reiterating this one year later. Still love the app, but I would use it regularly if I could “set” which Play categories I wanted and they would stay set every time I opened the app
App provides great instructions with practice sessions. Very pleased. Highly recommended.
Great lessons, but it quickly becomes too easy. You'll never get good at mental math if you have to rely on multiple choice questions. There should be a difficulty option where you have to type and submit the answer. Also, since I'm a teacher I'd like to be able to set a timer and and a specific number of problems and have a score at the end.
We love the strategies and the app. But my 3rd grade daughter cannot practice because all the numbers are at an advanced level. She wanted to practice her 4’s but she got 4 Times 66. That’s pretty tough for a 3rd grader. Can you add something in the settings to simplify the practice?
