Frequently Asked Questions (FAQs)

1. What is the most powerful graphing calculator?

The TI-NSpire by Texas Instruments is arguably the most powerful and reliable calculator you can buy. The two different types of TI-NSpire—the CX II and the CX II CAS—are both great options for math students handling coursework or about to tackle national exams (SATs and ACTs).

2. Which TI graphing calculator is the best?

The Texas Instruments TI-84 Plus CE (view at Amazon) is the best overall graphing calculator because of the value it offers: it has an excellent colored back-lit display, is rechargeable, and has the most popular applications preloaded.

3. What's the difference between TI-84 and TI-84 Plus?

There is no original TI-84, only the TI-84 Plus, the TI-84 Plus Silver Edition models, and the TI-84 Plus CE. The TI-84 Plus is an enhanced version of the TI-83 Plus. The key-by-key correspondence is relatively the same, but the 84 features some improved hardware.

4. What calculator is equivalent to the TI-84?

Its competitor for the TI-84 Plus, the fx-9860GII, has an MSRP of $79.99. Its best-selling model, the fx-9750 GII, has an MSRP of $49.99. Despite the lower prices Casio says it still turns a profit on sales of the calculators. But graphing calculators are a market where price isn't especially important.
