The all-purpose TI-84 Plus graphing calculator features more than a dozen preloaded apps including functionality that encourages exploration of interactive geometry, inequality graphing, and real-world data collection and analysis. Ideal for middle school through college.

Product Features

  • Real and complex numbers calculated to 14-digit accuracy and displayed with 10 digits plus a 2-digit exponent. Graphs 10 rectangular functions, 6 parametric expressions, 6 polar expressions, and 3 recursively-defined sequences. Up to 10 graphing functions defined, saved, graphed, and analyzed at one time.
  • Sequence graphing mode shows time series plot, cobweb/stair-step plot, and phase plots. User-defined list names. Lists store up to 999 elements. 14 interactive zoom features. Numeric evaluations given in table format for all graphing modes.
  • Interactive analysis of function values, roots, maximums, minimums, integrals, and derivatives. 7 different graph styles for differentiating the look of each graph drawn. Horizontal and vertical split- screen options. Stores up to 10 – 50×50 matrices.
  • Matrix operations including inverse, determinant, transpose, augment, reduced row echelon form, and elementary row operations. Convert matrices to lists and vice-versa. List-based one- and two-variable statistical analysis, including logistic, sinusoidal, median-median, linear, logarithmic, exponential, power, quadratic polynomial, cubic polynomial, and quartic polynomial regression models.

You’d think there would be an app by now. I bought one of these 20 yrs ago for my oldest daughter when she started high school. She used it all the way through college. Same with each of my other children. So imagine my shock when this came up on the list of supplies needed for my oldest grandson when he started high school. I actually said ‘You’d think there would be an app for that.’ But no there isn’t.What can you say about a TI 84? It’s the same as its always been. Nothing new and different because math hasn’t changed…

Texas Instruments TI-84 Plus, Ol’ Reliable I have had one of these for 10 years just about. Recently had to buy a new one, due to the flooding in Baton Rouge. So… it’s safe to say it isnt waterproof? (Hah). As a college student, I have been using this same model calculator since about the 7th grade. Never fails me. Easy to use, great functions. Crisp buttons, and a sliding cover that helps keep it protected in your bag or desk.

Perfect College tool (for STEM majors) I have had this for over four years now. Replaced batteries twice. I used this during community college and still use it at work. Although there is an app that simulates this completely (Wabbitemu), there is no replacing the real thing. Plus you can take this into exams (unless graphing calculators are not allowed.I think its memory functions are what make it so useful. I may have a few equations that I use all the time during a semester. I just plug them in y= and keep it there all…
