In class we will use either a TI-83 or TI-84. These calculators can be purchased on Amazon.com, at Walmart, Best Buy, Target, and most office supply stores. If you are unable to purchase your own graphing calculator, you are welcome to download a graphing calculator app for your smartphone (Desmos) or download the free graphing calculator for your computer linked below. These calculators will not be allowed in class, on tests or on quizzes. They will purely be for homework purposes. There is a classroom set of calculators available for use during class time.
