Introduction into complex numbers

In school we have been taught that √(-1) has no solutions, but what if it did. In 1545 an italian mathematician called Gerolamo Cardanoin thought why don’t we just assign √(-1) a variable and this created our imaginary unit i. Imaginary numbers are just the product of the imaginary unit i with any real number b so it can be written as bi. This is similar to the real numbers as our real unit is just 1 instead of i.

Complex numbers are the combination of a real number and an imaginary number so it can be written as a+bi
