how accurate is the emulator compared to an actual TI-84, especially with the more obscure functions like the finance solver or piecewise expressions during exams?
@eyda9fhu Great question! The goal is to match the behavior of a real TI-84 as closely as possible for the features students use every day.
Core math, statistics, lists, matrices, and exam workflows are my top priority. Some of the more specialized features (like the Finance Solver and certain edge cases with piecewise expressions) are still being tested and refined.
Are there any specific functions or exam scenarios you’d like to see verified? I’d be happy to prioritize those and let you know once they’re covered.
genuinely impressed that the embeddable iframe works cleanly on the page itself without me even having to dig for it. makes sharing with my tutoring students way less friction than digging through a doc.
@nermink6755 Thanks, Nermin! That’s exactly the kind of workflow I was hoping to support.
It’s great to hear you’re using the iframe with your tutoring students. I’m curious—what subjects are you teaching? I’d love to learn how you’re using it in practice and whether there’s anything that would make it even better for your classes.
