A complex number can be written in the form a + bi where a and b are real numbers (including 0) and i is an imaginary number. Therefore a complex number contains two 'parts': one that is real; and another part that is imaginary; note: Even though complex have an imaginary part, there are actually many real life applications of these "imaginary" numbers including oscillating springs and electronics. Examples of a …
