In this unit, we revise the basic ideas of natural numbers and we use them to practise the following operations: addition, multiplication, division and powers. The numbers that appear in each window are generated at random. This allows you to use the window indefinitely and practise a lot of different exercises. Numbers consist of only one or two figures so the calculations can easily be done mentally. Magic squares with sums and multiplications are used in the exercises, however the main objective of this unit is to learn things about natural numbers.
