Picky point: > Let’s just say that for our purposes we can think of complex numbers existing on a line perpindicular to our regular number line. If you take a piece of graph paper and mark a line from left to right, and then another line that crosses that line at 90 degrees, from top to bottom, you can imagine that the horizontal line represents the real number line, and the vertical line represents the complex number line. The vertical line is the imaginary number line. 2 is as much a complex number as 3i is (2 + 0i vs 0 + 3i).
