About TI-84Calc.com
Last updated: [Month Year]
We built TI-84Calc.com to solve one specific, ordinary problem: a student needs a graphing calculator right now, and either doesn't own one, forgot it at school, or can't afford the $100 to $170 a physical Texas Instruments calculator usually costs.
What we offer
This site provides free, browser-based calculators built to match the menus, functions, and button layout of real Texas Instruments devices, including the TI-84 Plus CE, TI-83, TI-85, and TI-30XS MultiView. Alongside the calculators, we publish guides that cover how to actually use them: graphing steps, statistics functions, model comparisons, and honest answers to the questions students and parents ask us most, like which calculator is allowed on the SAT, or whether an old calculator found in a drawer is still worth using.
Our approach to accuracy
Every specification, exam policy, and product detail we publish is checked against Texas Instruments' own documentation or other primary sources, such as the College Board and ACT's official calculator policies. When a policy or product changes, we update the relevant page rather than leaving outdated information live. We would rather tell you plainly that we're not certain about something than guess and get it wrong.
Who runs this site
TI-84Calc.com is maintained by an independent team focused on calculator tools and math education content. [Add a short, real paragraph here: your name, background, and why you built this site. A specific, true detail, like your own math background or teaching experience, does more for this page than anything generic ever could.]
Independence
TI-84Calc.com is not affiliated with, endorsed by, or sponsored by Texas Instruments. TI-84, TI-83, TI-85, TI-30XS, and related names are trademarks of Texas Instruments Incorporated. We built independent tools that match their calculators' interfaces because not everyone can access the real hardware, not because we're claiming to be Texas Instruments.
