The full version of the Correct and Quick Arithmetic Premium app is available especially for schools. The app is free of advertising. With Family Sharing set up, up to six family members can use this app. Correct and Quick Arithmetic Premium does exactly what the name predicts. First practice the basic calculations, and then speed it up. This app was developed for everyone who would like to train and maintain the basic processes of arithmetic. In this app you will find exercises with number bonds to 10, addition and subtraction sums up to 100, and the multiplication and division tables up to and including 10. These are the foundations needed for arithmetic. The ultimate goal is to have committed to memory the answers to number bonds to 10, addition and subtraction sums up to 20, and the tables through 10 (within 2 seconds). For sums up to 100, the way to work them out is automated. No distractions in the app The appearance of the app is kept as simple as possible. Scores are not saved. Experience shows that in particular, those who are not so good in arithmetic, like this! The structure of the levels of mental arithmetic in the app: Number bonds to 10 Addition and Subtraction to 10 Addition and Subtraction to 20 Addition and Subtraction to 100 Multiplications tables from 0 to 5 and 10 Multiplications tables from 6 to 9 Division Tables from 1 to 5 and 10 Division Tables from 6 to 9 First start to practice without timing yourself. In practice mode (X), the correct answer appears after a wrong answer. Wrongly answered sums are always repeated. Only when this goes well will you be able to start training at speed. So first CORRECT and only then QUICK! Stick to the running order of the sums in the app! Practise the number bonds and the sums up to 10 until you can do them all well, and most importantly, fast. These are the most important sums in mental arithmetic!! Level button With this button you can choose between 1 Level or Mix of levels. After a series of sums, a smiley will show how many you got right and how many wrong. The more sums you get right, the happier the smiley is! Ultimately, the reward is realizing just how good it is to be able to do these calculations quickly and correctly. You'll find that the arithmetic that comes later will also go better and more quickly because of it. Correct and Quick Arithmetic Premium is an indispensable instrument, dependent on any method, for learning mental arithmetic! Have fun, and good luck with Correct and Quick Arithmetic Premium!
