Practise mental arithmetic for addition. To do this, it is important to recognise arithmetic advantages.

Mental arithmetic - subtract in your head!

We practise mental arithmetic problems for subtraction. For this purpose, almost all topics are structured according to difficulty. The tasks are not as difficult as they look at first glance.

Multiplication 🤔 Double, triple, ... , square numbers

Multiplication in your head. To do this, you have to master the multiplication tables. You also use written multiplication in your head.

Example: 14 times 14 is 10 times 14 plus 4 times 14.

10 times 14 is 140.
4 times 14 is 56.

Together, that's 196, so 14 times 14 equals 196.

You should know the square numbers up to 20 by heart by grade 5 at the latest!

Division 🤔 Halve, ... - all in the head!

Divide by 5 also means: calculate times 2 and then divide by 10.

A simple example: 160 : 5

Now divide 320 by 10, crossing out only the last zero. The result is 32 and you're done!
