The New TI-84 Evo
Some Notes on the TI-84 Evo
The TI-84 Evo was released on April 28, 2026 in the United States. It is an update of the TI-84 CE Python and in fact, replacing the TI-84 CE Python. As of right now, the TI graphing calculator the TI-83/84 family consists of:
TI-83 Plus: This calculator model was first introduced in 1999 and is run by four AAA batteries with a CR1620 backup.
TI-84 Plus: This is the base TI-84 model with a monochrome screen, originally first arrived in 2004. The last firmware, 2.55, adds math print (textbook print).
TI-84 Plus CE: This is a color version of the TI-84 Plus and has a rechargeable battery.
TI-84 Evo: This is next version of a TI-84 Plus that has Python.
Quick Facts and What the TI-84 Evo Can Do

For reference, the TI-84 Plus CE Python, the calculator the TI-84 Evo replaces, was in production from July 27, 2021 to April 27, 2026.
At this point we all know, more or less, the main features of the TI-84 Plus, as they are present with the current TI-84 Evo (not an all inclusive list):
* Graph up to 10 functions, six parametric functions, six polar functions, and three recursive functions
* Lists can have up to 999 elements can be used. Lists can have real and complex numbers. There are many functions associated with lists, such as sorting, finding the arithmetic average (mean), the sum of the elements, applying lists in statistical analysis, and generating lists from defining a sequence. There are six lists that can be accessed from the keyboard and additional lists with custom names can be created.
* Complex numbers including arithmetic, conjugate, conversion between rectangular (a+bi) and polar forms (re^(iΘ)), square, square root, cube, and cube root of complex numbers.
* 10 matrices, [ A ] through [ J ], including the transpose, inverse, determinant, row operations, and generating identity matrices.
* Many statistical regressions, distributions (normal, student, Chi-squared, F, binomial, Poisson), and ANOVA.
* Drawing tools
* Two programming languages: the classic TI-Basic and Python. Python modules include math, random, plotlib (TI version), time, specialized modules for the TI hub, TI rover, and import processing.
Two major selling points of the TI-84 Evo are:
* Distraction free mathematics with no smartphone interface. However, all calculators that are not downloaded to smartphones qualify to be “distraction free”. This is a response to curbing smartphone use in the classroom.
* The TI-84 Evo has an icon menu. The icon main menu replaces the app key. While the TI-84 Evo is on, the [ on ] key acts as toggle between the main menu and the last used app.
The apps included with the TI-84 Evo are:
1. Calculator (Home)
2. Y= Function Editor (same as pressing [Y=]
3. List Editor (same as pressing [ stat ], [ 1 ])
4. Mode Settings (same as pressing [ mode ])
5. Numeric Solver (same as pressing [math], C or [math], [ ↑ ], [ enter ])
6. Polynomial Root Finder
7. System Solver (linear systems)
8. Finance (time value of money solver and basic finance functions, including date functions covering years from 1980 to 2079).
9. Transformation Graphing
Inequality Graphing
Conics Graphing
Python
TI-Basic

Some Differences Between the TI-84 Evo and the Previous TI-84 Plus CE Python
For this section, I refer the TI-84 Plus CE Python as the 84 Python and the TI-84 Evo as the 84 Evo. These are some of the changes observed. Despite these changes, at its core the TI-84 Evo is easy to pick up and learn, and if you are transferring from an older TI-82/83/84, the learning curve is at the most, minimal.
Keyboard Changes:
84 Python: smaller keys, 2nd and alpha functions printed above the keys
84 Evo: big square keys, 2nd and alpha functions printed on the keys
From the 84 Python to the 84 Evo:
2nd of [del] key: ins becomes an icon | <> []
distr (distributions): moves from 2nd of [vars] to alpha of [stat]
[apps] key replaced with fraction template [ []/[] ]
2nd of [math] key: test becomes an icon =≤≠>
matrix: moves from 2nd of [x^-1] key to 2nd of [vars] key
[clear] key gets an undo clear 2nd function, labeled ⟲clear, can be used as "cut"/"copy" and "paste"
[x^-1] reciprocal key becomes [x^[]] power key template, while its 2nd function is the root template []√
Arithmetic keys move up a row:
[ ^ ] becomes the [ ÷ ] key
[ ÷ ] becomes the [ × ] key
[ × ] becomes the [ - ] key
[ - ] becomes the [ + ] key
[ + ] becomes the [ <> ] key (utility/toggle key) Though the primary functions change the 2nd and alpha functions remain the same
[enter] key appears to lose the solve alpha function
2nd of [sto→] key: rcl gets lengthened to recall
[on] key gets a home icon
Battery:
84 Python: Lithium ion polymer
84 Evo: Lithium ion
Power Connection:
84 Python: TI-specific cord with USB-A/USB-mini
84 Evo: USB-C/USB-A (came in the box)
Colors of the keys – on the white keyboard:
84 Python: blue 2nd key, green alpha key, black math keys, gray arithmetic keys, white number keys, gray function and arrow keys
84 Evo: blue 2nd key, green alpha key, white math, arithmetic, and function keys, black arrow and number keys
number keys: [ 0 ] through [ 9 ], [ . ], [(-)]
Connection Software:
84 Python: TI Connect CE
84 Evo: https://connectevo.ti.com/ticevo/en/ (online connection, like TI-nSpire CX II)
Multiplication Symbol Used in Expressions:
84 Python: asterisk (*)
84 Evo: dot (⋅)
Colors Used on Calculations on the Home/Calculator Screen:
84 Python: Everything is in black
84 Evo: Input expressions are in black, cursor is blue, answers are in green
Memory Available for Storage:
84 Python: 3 MB
84 Evo: 3.5 MB
Graphing Display Area:
84 Python: 264 x 165 pixels with a border around the graphing
84 Evo: 319 x 209 with no boarder as the graph takes the entire screen (just like the old days, the monochrome TI-84)
Backwards Capability of TI-83 Plus and TI-84 Plus TI-Basic Programs:
84 Python: Yes (.8xp)
84 Evo: No (.8xp2). Why? Texas Instruments rewrote the Basic language engine. There are programs that can translate from .8xp to .8xp2 files. Check Cemetech or TI Planet.
Note: Python programs can be transferred easily between the 84 Python and 84 Evo.
Built in Clock:
Python: Set clock option present
Evo: No clock option present (quiet removal, will the clock be missed?)
Features Added to the TI-84 Evo
* Gradian mode, with all the conversions and symbols added
* Three additional regressions: PropReg (y = a*x), RecipReg (y = a/x + b), and eBaseReg regression (y = a * e^(b*x))
* The Time Module adds two additional functions: ticks_ms and ticks_diff.
Should I Get a TI-84 Evo or TI-84 CE Python?
Reasons to buy the TI-84 Evo:
You like connecting with USB C instead of USB Mini
Faster processor
Your first TI-84 ever
You desire to work with both hardware and the emulator (you get a four year license on purchase)
You want the latest model and/or if you are like me and like to collect calculators
Reasons to buy the now older TI-84 CE Python:
The border around the graphing screen isn't annoying, don’t mind it as much (or at all)
You work with the SciTools and Periodic Table apps a lot
You want a TI-84 with Python at a lower price
You work with the Turtle Module in Python
Note: If you want assembly programming with a TI, stick with the older monochrome calculators as the newer TI calculators no longer support assembly programs.
