Addition And Subtraction Of Complex Numbers Worksheet

                    Lesson 1

                                                           In adding or subtracting complex numbers, add or subtract the real component with the real components. Then add

                                                            or subtract the imaginary components with the imaginary components.

                                                (a + bi) + (c + di) = (a + c) + i(b + d)

Problem:                   Solve the problem. Express the result in a + bi form.

(6 + 3i) + (2 - 3i)

Solution                    Add the real components i.e. 6 + 2 = 8

Step 1:  

Solution Add the imaginary components i.e. 3i – 3i = 0

Step 2:                        

Solution Express your answer as: 8

Step 3:           

                                                            Solution                    The answer is: 8

 Step 3:                                                                      

 Complete   

                                                            Try two practice problems:  

Solve the problems. Express the result in a + bi form.

A.	(3 + 4i) + (4 - 3i)
B.	(7 + 6i) - (4 - 2i)
