Focus C: Adding and Subtracting Complex Numbers

Step E

• When a complex number, a + bi, is expressed as an ordered pair, (a, b), the first coordinate is the real coefficient and the second coordinate is the coefficient of the imaginary part.
• Therefore, add the first coordinates together, and then add the second coordinates together. For example (3, -4) + (5, 2) = (8, -2).
