</blockquote><div><br>Not quite. Consider the square root of -1. It's not real because you can't square a real number and get a negative, so we define "i" (or, perhaps "j") to be the square root of -1. An imaginary number is of the form Ai, where A is "real". So 2i, -
3.14i are imaginary.<br><br>Complex Numbers are of the form A + Bi Where A and B are real (so they have a "real" component and am "imaginary" component). So yo might see 2 + 3i, etc. You'll see them a lot in engineering.
