Operations with integers II  
INTRODUCCTION  
In this unit, we revise
the basic ideas of integers and we use them to practise the following
operations: sum, 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. The numbers consist
of only one or two figures so the calculations can easily be done mentally.
