Rent and Sell
Welcome to Calctus!
We have a wide variety of calculators for you to rent and sell!
Calctus is a unique on campus experience for renting and selling calculators! We have made it easy to do so with our on-campus locations that allow students to have easier access to our calculators. 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!

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
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.
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.
