Texas Instruments (TI) are our calculators of choice. There are many other great companies – so this is a personal preference.

- Algebra, Geometry, Biology, Chemistry
- Algebra 2 with Trig, Calculus, Physics, Statistics, and beyond – These courses require a bit more horsepower and some graphical tools. Our choice is the TI-84 Plus CE.

Note: The TI-84 Plus CE is approved for use on the following exams: PSAT, SAT, and ACT college entrance exams and AP Exams that allow or require a graphing calculator.

**Web Base Calculators**

Scientists and engineers are using more powerful tools today. One such tool that is **FREE** to use is Wolfram Alpha. It has APPS and extensions for web browsers etc. If you ask us a question on support, this is the tool we use. But, you cannot take it into the ACT/SAT or other tests – so you need to be able to use your calculator.

**Emulators**

Emulators are software programs that operate like the calculator. While you can still find them (search the web for “TI calculator emulators”), these are just not as important given all the other tools available.
