Overview
Not a basic scientific calculator, this Texas Instruments model graphs functions, parametric and polar curves and sequences, then analyzes roots, extrema, integrals and derivatives. It also handles matrices, lists and a wide set of statistics tests on a multi-line LCD.
Graphing, matrix work and statistical testing in one handheld covers a full high school and early college math sequence. The listing does not say what cables or software come in the box, so plan on batteries only.
Who it's for
Students working through graphs, regressions and hypothesis tests will use most of its functions. Someone balancing a checkbook or doing simple unit conversions needs far less calculator.
Pros and cons
- Graphs several function types
- Matrix operations including inverse and determinant
- Broad regression models
- Hypothesis tests and confidence intervals
- No cables or software listed in box
- Weight and dimensions not listed
- Runs on disposable batteries
Performance notes
Results depend on mode: function, parametric, polar and sequence graphing each have their own setup, and the table view shows numeric values for every mode. Zoom tools and graph styles help separate overlapping curves. Statistics run from lists, so data entry into lists comes before any regression or test.

Frequently asked questions
What comes in the box with the TI-84 Plus?
The listing confirms the calculator and its 4 AAA batteries. It does not list a cable, case or software, so do not count on them.
Can the TI-84 Plus do statistics?
Yes. It runs list-based one- and two-variable statistics, many regression models, 9 hypothesis tests, 6 confidence intervals and one-way analysis of variance.
How many functions can the TI-84 Plus graph at once?
Up to 10 graphing functions can be defined, saved, graphed and analyzed at one time.
Does the TI-84 Plus handle matrices?
Yes. It stores up to 10 matrices of 50x50 and performs inverse, determinant, transpose, augment and reduced row echelon form.
Is the TI-84 Plus a color screen model?
The listing describes an LCD multi-line display and does not mention color.
