I’ve been building random problem generators for student HW/practice for the last year, and every so often, one student might ask a question about why their answer is marked incorrect (when it actually is correct). After a year, I think I finally figured out why and it may be related to Desmos background calculation speed and how fast students are submitting their answers.
Here’s a short video describing the issue: https://drive.google.com/file/d/1blqpGBh_OYrlujqOtEFpgTLNdFBBzR0i/view

Let me know if there are any workarounds that I could use to “disable” the enter key to act as a button press or a way to disable the button completely for the first 500 milliseconds or something upon changing the input
Thanks in advance!
Edit: I was looking at my video one more time and it looks like when the enter key is pressed really quickly, the button has an issue capturing. (studentslopeh and student yinth are lastvalue variables and they appear as NaN when the enter key is pressed quickly)
