Correct and Quick Arithmetic

Correct and Quick Arithmetic 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.

The ultimate goal is to have committed to memory the answers to addition and subtraction sums up to 20, and the tables through 10 (within 2 seconds). The sums are subsequently memorized.

You decide which type of sum you want to practice.
You don't know? Stick to the order of the sums in the app.

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!

Have fun, and good luck with Correct and Quick Arithmetic!
