Operations on Numbers

Lesson 3 consists of providing you with a Self-Tutorial on the typical operations done on numbers. These include: absolute value, opposites, addition, subtraction, multiplication, division and simple exponents. Order of Operations is covered in detail. I also explain how to use your graphing calculator to help you perform all these operations. Unfortunately, when these videos were made, I used a cheap wireless microphone, so you will hear an occasional “pop” and “buzz” sound when I am talking. I am sorry about this. The discs are not damaged. I have a new microphone now, so new lessons will be of a much higher quality.
