Grandmathster app for iPhone and iPad

Do you want to improve your mental math skills and ability to do arithmetic fast in your head? Grandmathster can help you master your ability to do calculations quickly.

Grandmathster gives players the choice of answering questions on addition, subtraction, multiplication, division, or a mixed operation mode. This app allows different levels of customization to each game mode - such as the option to select your desired number of questions to solve or to focus on specific digits only (e.g. exclusively working on multiples of 7). Additionally, players are able to keep track of their top scores and unlock different badges throughout the game.

Grandmathster is great for young children looking to practice their arithmetic facts or for adults looking to increase their speed. High school students can use Grandmathster to help prepare them for the portions of the SAT and PSAT that do not allow a calculator.
