Rent, Sell & Buy Calculators!

Welcome to Calxie!

We have a wide variety of calculators for you to rent and sell!

Calxie is a unique on campus experience for renting and selling calculators! We have made renting a calculator as easy as possible. We help students save money by renting our calculators for the classes you need them for, rather than having you purchase a calculator at full price that you may never use again after that class!

Unlike other rentals, Calxie works with schools so instead of waiting for your calculator in the mail or having to go and pick it up, Calxie sends students calculators to their teacher to distribute. By doing this, you do not have to worry about getting a calculator in time for back to school. Additionally, it removes the extra step of going out and buying one from somewhere else. From Calxie to the teacher. That’s it! That’s all there is to it!

Texas Instruments TI-84 Plus CE Color Graphing Calculator
$2.49 every month

The Texas Instruments TI-84 Plus CE Color Graphing Calculator is a lightweight, color-screen graphing calculator designed for secondary and college-level math and science courses. It combines a familiar TI-84 family interface with a high-resolution, full-color backlit display and improved portability while retaining exam approval (including many standardized tests where graphing calculators are allowed).

Key features of Used TI-84 Plus CE

  • Display: 320 × 240 pixels, full-color backlit screen that renders graphs, plots, and menus with clear visual distinction for multiple functions or data sets.

  • Form factor: Slim, rechargeable design that is significantly thinner and lighter than earlier TI-84 models; removable hard slide case for protection.

  • Battery: Built-in rechargeable lithium-ion battery with USB charging; long battery life for classroom use and standardized testing.

  • Memory and performance: Increased RAM and internal storage compared with TI-84 Plus (non-CE) models, allowing for more apps, programs, and large data sets; faster processor for smoother graphing and computation.

  • Connectivity: USB port for connecting to computers and other TI calculators; supports file transfer, OS updates, and classroom connectivity.

  • Operating system and compatibility: Runs TI-84 Plus CE OS with compatibility for many TI-83/84 programs and TI-Basic apps; also supports Python on many later firmware versions and CE hardware variants (availability may depend on specific model and OS version).

  • Built-in functions: Comprehensive set of math and science functions including graphing (function, parametric, polar, sequence), statistics, regression models, matrices, complex numbers, calculus tools (numeric derivative and integral), finance functions, and equation solving.

  • Apps and customization: Preloaded apps (such as Cabri Jr., Periodic Table, Polynomial Root Finder) with support for additional apps and user programs; customizable color palettes and graph styles.

  • Exam use: Approved for use on many standardized exams including PSAT/NMSQT, SAT, ACT (check current exam policies), AP exams, and many state-level tests — subject to the latest rules and allowed-device lists.

Typical users and use cases

  • High school students studying algebra, geometry, trigonometry, precalculus, AP Calculus, and AP Statistics.

  • College students in introductory STEM courses needing reliable graphing, statistical analysis, and computational tools.

  • Educators and classroom settings using TI technology for demonstrations, student activities, and standardized-test preparation.

Pros

  • Familiar TI-84 layout and menu structure with modern color display, also found on the newer TI-84 evo calculator.

  • Lightweight and rechargeable — easy to carry and maintain.

  • Strong ecosystem: wide availability of educational resources, apps, and community programs.

  • Good balance of ease-of-use and functionality for classroom and exam settings.

Cons

  • More limited computational power and advanced symbolic algebra compared with CAS (computer algebra system) calculators.

  • Color and Python support vary by firmware and specific CE revision; confirm features before purchase if those are essential.

  • Not optimized for heavy symbolic manipulation or advanced engineering-specific toolchains.

The TI-84 Plus CE Color Graphing Calculator delivers the trusted functionality students expect from the TI-84 series in a sleek, modern design. With a vibrant color display, slim and lightweight body, and rechargeable battery, it offers a convenient way to handle graphs, equations, statistics, and other essential calculations.

Choosing a Used TI-84 Plus CE can be a cost-effective option for students who want reliable graphing capabilities without paying the price of a new calculator, so you can buy a used graphing calculator with confidence. It is ideal for high school and early college coursework, standardized testing, and everyday math and science classes. With its familiar interface and portable design, the TI-84 Plus CE makes it easy to work through complex problems both in and out of the classroom.

The TI-84 Plus CE is one of the most commonly used models in many science and math fields. It brings color into the life of Texas Instrument calculators, allowing students to graph different data and compare and contrast results!

This calculator holds a strong and steady amount of power that can last for weeks on a single charge!

This calculator is a must have for the SAT, ACT, and/or AP and IB tests! It is easy to use and includes finance and science programs allowing students to use this calculator over multiple subjects!

Get Your Graphing Calcs

Finding the best graphing calculator should not empty your savings. High school and college math classes demand reliable computational models like the Texas Instruments TI-84 series, but retail tags remain high.

  • Save money compared to purchasing brand-new retail units

  • Rent for specific terms without long-term financial commitments

  • Skip hefty upfront store prices

Simple Student Savings

Math courses move quickly. Having a trusted handheld computational device changes things when midterms arrive. Students often require advanced plotting capabilities for algebra, calculus, and statistics homework.

  • Lightweight portable designs fit right into backpacks

  • Rechargeable batteries last through weeks of heavy daily testing

Renting provides an easy path forward. Instead of paying full price for a tool used only a few months out of the year, short-term plans keep academic expenses manageable. Every device arrives clean, tested, and ready for classroom use. Pick a plan, finish the term, and send it back. Simple math.
