About this exercise
The generator shows a rectangular array of dots. Your job is to find out how many there are altogether — either by counting them or by multiplying rows × columns.
How to practise
Count the rows and the columns. Multiply them and you have the answer. It helps to picture each row as containing the same number of dots.
