About Arismetica

• Practice the four operations
• It's free!
• Easy to use on a computer, tablet or mobile
• Practice at any time with short, quick exercises

The four operations form the basis of all mathematics, so it is important that you master them fully. With Arismetica, it is easy to practice - just choose the operation type and difficulty level, and start practicing right now - no registration required and completely free.

You practice with short, specially designed time-limited exercises. The time limit encourages you to quickly try to remember, rather than calculating them. The goal is that these calculations become automatic, so you don't have to think about it, you just know the answers.

Like all new skills, the four operations require time and practice. In order to achieve results, continuous practice is recommended over a length of time, e.g. shorter practice sessions of 10-15 minutes a day, 4-5 times a week. The results are saved so you can see how it went the last few times and work on any weaknesses.

Arismetica can be used in any current browser and because the interface adapts to the device being used, Arismetica works just as well on a computer, tablet or mobile.
