1
What is the imaginary unit i ? What is a complex number? Identify the imaginary and real parts of a complex number. Practice - see textbook p.103 #7 – 42 1.3 Complex Numbers http://www.youtube.com/watch?v=NeTRNpBI17I

2
Add and Subtract Complex Numbers Practice - see textbook p.103 #43 - 50 Add the real parts and the imaginary parts, just like combining like terms. Be sure to distribute the negative sign when subtracting! http://www.youtube.com/watch?v=eyy_SR1JfyQ&feature=youtu.be

http://www.youtube.com/watch?v=O9xQaIi0NX0 Multiplying easy complex numbers * Remember i 2 = -1

4
Multiplying complex numbers Practice - see textbook p.103 #51- 68 http://www.youtube.com/watch?v=Fmr3o2zkwLM&feature=youtu.be

5
Complex numbers and their conjugate The conjugate of a complex number is simply the same complex number with the sign changed on the imaginary part. When you multiply a complex number by the conjugate, the product simplifies to a real number with no imaginary part. Complex conjugates are needed for division of complex numbers. http://www.youtube.com/watch?v=VbOzEkvMb_A&feature=youtu.be

6
Dividing complex numbers To divide complex numbers, multiply the numerator and denominator by the conjugate of the denominator and simplify. Practice - see textbook p.103 #69 – 80 http://www.youtube.com/watch?v=XBJjbJAwM1c
