GRAPHING
TI-84 Calculator Online
The graphing calculator most U.S. high schools use. Graph functions, run 1-Var Stats and regression, use the normal distribution and practice for the SAT, ACT and AP exams. Comes with a 9-step guide.
GRAPHING, COLOR
TI-84 Plus CE Calculator Online
The color edition of the TI-84. Learn color graphs, grid lines and the ALPHA shortcut menus, and see how the CE compares with the older TI-84 Plus before you buy one.
GRAPHING, CLASSIC
TI-83 Calculator Online
A TI-83 style graphing calculator for schools that still use the older model. Graph up to four functions, trace, zoom, see tables and run 1-Var Stats and LinReg.
SCIENTIFIC
TI-30XS Calculator Online
A scientific calculator laid out like the TI-30XS. Trig, logs, powers, roots and memory for Algebra, Geometry and Chemistry, and good practice for the GED, SAT and ACT.
QUICK PLOTS
Free Online Graphing Calculator
Not a TI model, but handy. Type an equation and the graph appears. Compare several functions, find zeros and intersections with a click and explore with sliders.

| Tests that ban graphing calculators | TI-30XS |
TI Graphing vs Scientific Calculators
Texas Instruments makes two main kinds of school calculators. Scientific calculators like the TI-30XS handle arithmetic, fractions, trig, logs and powers. They can’t draw graphs or store programs, which is why almost every test allows them. Graphing calculators like the TI-84 and TI-84 Plus CE do all of that and also plot functions, run full statistics and store lists and programs.
A simple rule: if your class draws graphs or runs regressions, you’ll want a TI-84. If you mostly need trig, logs and roots, or your test bans graphing models, a TI-30XS is enough. Read Is a TI-84 a Scientific Calculator? for the full breakdown.
Conclusion: The Right TI Calculator, Free in Your Browser
You don’t need to own every Texas Instruments calculator to practice on it. Use the TI-84 or TI-84 Plus CE for graphing classes, the TI-30XS for scientific-only work and the GED, and the graphing calculator when you just want to see an equation. Bookmark this page so all of them are one click away.
