It is best you have a TI 83, TI 83+, TI 84 or a TI Inspire
calculator. These calculators can be bought from Staples, 
Target, or Office Depot, or any school supplies tore

It is best that you have your own calculator for my 
math classes, Functions & Trigonometry, Consumer Mathematics, and SAT 
Preparation..

Please make sure you have an ample supply of pencils, pens, and note 
paper, without which you will not be able to gain very much learning 
in my classes.
