It is best to own your own calculator so that you will have access to it both in and out of class.  We recommend purchasing the TI30XS Multiview Calculator (pictured in materials list) if you do not already own a calculator.  There is a limited supply of calculators for loan in my classroom during each class period, but it will be safer to have your own calculator for your use.  If you need to purchase a TI30XS Multiview calculator and would like to purchase one through the school, use this link to order and pay for it.  Calculators purchased through the school will be engraved with the name of the student ordering it.

 

If you do not have your own calculator and borrow one each day from the classroom supply, this is the link for a free online calculator which works well for Advanced Algebra or for Pre-Calculus when you are outside of the classroom:                   https://www.desmos.com/scientific

 

There is also a post below about an app you can use on your phone outside of class.  However, you must have a handheld calculator for use in class for classwork and assignments as you will not be allowed to use the app or the website on your device.
