About Us — TI-84 Online Calculator

Who We Are

TI-84 Online Calculator (ti84onlinecalc.com) is a free, browser-based TI-84 Plus CE calculator simulator, built for students, educators, and anyone who needs TI-84 functionality without downloading or installing anything. The site is created and maintained by Muhammad Musadiq.

The calculator itself is free to use, with no account, signup, or payment required.

Background & Experience

Muhammad Musadiq has more than 18 years of experience in mathematics education and web development. This site was built to address a common, practical problem: students who need TI-84 functionality for homework, exam prep, or classroom work but don’t have consistent access to the physical device, which costs around $130.

Content on this site, including the error message guides, comparison articles, and tutorials, is written and reviewed based on direct testing against a physical TI-84 Plus CE, rather than generated and left unchecked.

How We Maintain Accuracy

Calculator functions and outputs shown on this site are checked against real TI-84 hardware. Content is reviewed and updated when Texas Instruments releases firmware changes, when exam calculator policies change, or when users report an error.
