Author's NotesLearn all the sums up to 100. Free!


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.

In this app you will find exercises with 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 addition and subtraction sums up to 20, and the tables through 10 (within 2 seconds). The sums are subsequently memorized.
For sums up to 100, the way to work them out is automated.

The structure of the levels of mental arithmetic in the app
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 sums up to 10 until you can do them all well, and most importantly, fast. These are the most important sums in mental arithmetic!!

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 is an instrument, not dependent on a method, for learning mental arithmetic!

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