The field C of complex numbers
... The usual way to quickly start with complex numbers is to say that we introduce a new object, which I will call i (engineers very often use j), such that the following characteristic property holds: i2 = −1. Now, having this new object at my disposal, I can easily define the set of complex numbers as ...

... for some mathematicians, a little unsettling. In fact, the idea of zero did not appear in mathematics until around the year 900. It is easy to see how the so-called natural numbers came by their name. Fingers, toes, trees, fish, etc., can all be counted, and the very concept of counting is what the ...

Notes on complex numbers
... next section). The complex numbers are great: they have addition, subtraction, multiplication, division (even by zero, as we’ll see later), they are complete, and all polynomials with coefficients that are complex numbers have solutions which are complex numbers (this fact is called the Fundamental ...
