Classroom graphing calculator

The TI-84 Plus is a classroom graphing calculator designed for secondary and university mathematics courses. It arrives new with pre-loaded applications for interactive geometry, inequality graphing and real-world data collection. The 8-line by 16-character display shows 10-digit results with a 2-digit exponent.

Battery power and thermal profile

The unit runs on four AAA batteries with a lithium backup that protects RAM memory during battery changes. There is no active cooling, so operation is silent and produces no noticeable heat during normal use. The low power draw supports extended classroom sessions.

Slide case and connectivity

An impact-resistant slide case shields the calculator in transit. A TI Connectivity Cable is included for linking with other TI products or a computer. The I/O port supports unit-to-unit communication and software updates. Buyers who need a computer-algebra system or a higher-resolution colour screen will need a different model.

Questions about this item

How do I install the batteries and keep the memory intact?

Insert four AAA batteries; the built-in lithium backup protects RAM during the swap so no data is lost.

Which power components will need replacement over time?

The four AAA cells are the only user-replaceable power source; the internal lithium backup is not designed to be changed.

How many graphing functions can I analyse at once before hitting the limit?

Up to ten functions can be defined, saved, graphed and analysed simultaneously.
