One by one golving an addition sum

In the first exercise of each group, the app conjures a sum on the screen and you must drag the correct answer behind the = sign. Later you also get an exercise where multiple sums are shown on a single screen.

Listen to the sum

In this exercise you listen to the voice that reads the sum. Next you have to type the answer with the calculator. In this way you learn to add up without making choices from possible answers on the screen.
