Do you usually solve math problems on the keyboard? With MathiO, you practice mental arithmetic using handwritten input.

Do you read all the numbers first to select the correct result? No. Then try out MathiO and practice mental arithmetic with handwritten input.
The user interface is deliberately kept clean and simple to avoid distractions from unnecessary graphics and animations and to allow you to concentrate on the calculation.

Number field entries are a thing of the past. With MathiO you practice the 4 basic arithmetic operations and size comparisons in different difficulty levels and categories and collect medals.
