The following worksheets will teach your students how to multiply and divide complex numbers correctly.

#### Any number that belongs on a number line, whether it is right or left of the zero, is referred to as a real number. There are numbers that actual don't belong on that number line at all. Those numbers are called complex numbers. Complex numbers are made by adding real numbers to something called imaginary numbers. Imaginary numbers are all multiples of something called an imaginary unit which is usually referred to as i. All the worksheets found here work on finding products and quotients of these complex numbers. The bulk of the worksheets work on products/quotients of complex numbers by applying the proper formula in order to balance the given equations.

These lessons and activities teach the steps for multiplying numbers in quadratic equations that contain imaginary numbers. Students will practice solving expressions and then take a short quiz to show they have learned the skill.
