What’s Different between TI-83 and TI-84?

Copyright © 2006–2015 by Stan Brown, Oak Road Systems

Summary: The TI-83 and TI-84 are nearly keystroke compatible, but the 84 has a few new functions that the 83 lacks. This page lists them.

In early 2010, TI released the 2.53MP operating system for TI-84s, with MathPrint and some other features. More features wre added in version 2.55MP, about a year later. See 83Plus:OS:OS 2.53MP Changes, and “new in 2.55MP” many places in this note. If you have a TI-84 Plus C (in color), you already have the latest OS. WIth other TI-84s, press [2nd + makes MEM] [1] and check your firmware version. If it’s less than 2.55MP, it’s worth your while to upgrade the OS to get the new features.

Differences between TI-83 Silver and TI-84 Silver


Both the TI-84 Plus and the TI-84 Silver now come with these features:

You can control these features (except as indicated) by pressing [MODE] [].


The keyboards are identical in labeling, but the 84’s design is curved, and all keys except the numeric keypad are smaller.

new in 2.55MP: On the home screen, you can just press [] repeatedly to recall past calculations. When you find the one you want, press [ENTER] it’s pasted to the screen where you can edit it if you wish before pressing [ENTER] again to execute it. ([2nd ENTER makes ENTRY] still works.

The 84 has a clock, which you can view or set by pressing [MODE].

new in 2.55MP: Four new “shortcut menus” claim to offer faster access to existing functions; press [ALPHA F1 makes FRAC], [ALPHA F2 makes FUNC], [ALPHA F3 makes MTRX], [ALPHA F4 makes YVAR]. Of these, [ALPHA F3 makes MTRX] really does seem to make it easier to enter matrices.

There are a few goodies for statistics students:

Catalog Functions

The following catalog functions are in the 84 but not the 83:

The included Catalog Help application doesn’t describe these. Consult Appendix A of the Guidebook for the use of these catalog entries — except for ExecLib and OpenLib, which seem to be undocumented.

Differences between TI-84 Plus and TI-84 Plus Silver Edition

This page compares the two models I have, the TI-83 Plus Silver Edition and the TI-84 Plus Silver Edition. I know of only these differences between the plain TI-84 Plus and the Silver Edition:

If you have a plain TI-84 Plus, I’d be grateful for a report of any of the functions listed above that your calculator doesn’t have.
