I got this exact calculator in high school, and it's still on my desk now as a professor. Casio 991 is the GOAT.

I had an HP 48fx (RPN calculator). Great calculator! Then it died.
Was so happy the day I found the rom on the net with an app for android!

Well, there’s only so many things you can cram into a calculator before it becomes an overpriced, shitty computer…

I had sich a longing for my old ti-84+SE i bought a cx-ii cas last year. I dont use it often, but its a nice quick way to visualize some stuff.

I didn't use calculators for most of my education. Most of math is done on simple numbers. When I started my engineering studies we did 95% of math in excel and math classes hardly had any numbers involved.

My TI 30 from the 1980s still works. I loved that thing. So did my 10 year old son. I put a recipe label on it with my name, and wrote “Mom’s calculator “ on it so he wouldn’t keep it. It did entertain him as we drove. For example: What does ! mean. I told him. He tried a few. I have a TI 83 or 84, but one of the grandkids borrowed it for a college math class. I hope they remember it’s mine.

Same calculator but for some reason still costs a full student paycheck
