I’m old enough to have Opinions on calculators as a tool. And I never cared for the TI series. I really liked the HPs. I had an HP 48G that I used from 1997 in high school through engineering school and well into my professional career. And it died circa 2018 and I am still sad about it.
That being said, this TI-30X IIS is my second favorite calculator I’ve used intensively. Got me through grad school. It’s like, $15. It’s solar! I got the bright pink color and I can see that I left it on the table a mile away. It’s solar. It’s got a nice edit line. Great function set. I kinda want to buy the teacher pack of 10 and give them away as party favors.
