Algebra

It is strongly recommended that you get a TI-84+ Calculator.

Acceptable alternatives are TI-84 CE and TI-83+.

Will work but less acceptable TI-83, TI-85, TI-86, TI-81, TI-82. These loose some of the newest functionality.

Recommended places to search are: Craigslist, Facebook Marketplace, or eBay.

Android users please download Wabbitemu (download the Calculator's Operating System) or Calculator X84.

Chromebook users download TI-84 Plus CE App for Chrome OS

iOS users please download Calculator X84 or GraphNCalc83. You will not have advanced features in the free version.

For Windows and Mac OS download Wabbitemu. You will need to download the Calculator's Operating System.
