Speed Sums: Addition

Use speed sums to help improve your mental arithmetic. This app is great for kids or adults who want to sharpen up their arithmetic abilities, or anyone who enjoys logic, or puzzle games.

Players are given a series of progressively harder questions to add up with a time limit of 10 seconds per question. For every correct answer you get 10 points, and your high score is recorded so you can keep track of your progress.

There are also social features allowing you to share your scores with your friends through social networks like Twitter and Facebook.

This app focuses on addition, but EduApp is producing a whole series of free and paid apps covering addition, subtraction, multiplication and division, as well as apps aimed at the syllabuses of British Maths and Science courses.

EduApp also produce tools for teachers, such as our app Quiet Classroom, which helps teachers reduce noise in their classrooms.
