Imaginary numbers work the same, except that you can rotate part way. If we say 'go east by 2 Г— -3 miles', it means 'rotate all of the way around (so that you are now facing west) and go 2Г—3 = 6 miles'. Multiplying two imaginary numbers is a lot like multiplying a positive number with a negative number. If we say 'go east by 1 + i miles' it means the same as if we had said 'go east by one mile and north by one mile'. Similarly, if we say 'go east by -i mile', it means the same as if we had said 'go south by 1 mile'.ДЄdding is easy too. If we say 'go east by i miles', it means the same thing as if we had said 'go north by 1 mile'.

If we say 'go east by -1 mile', it is the same as if we had said 'go west by 1 mile'. One way of thinking about imaginary numbers is to say that they are to negative numbers what negative numbers are to positive numbers. Imaginary numbers are numbers that are made from combining a real number with the imaginary unit, called i, where i is defined as i 2 = в€’ 1.
