In the course of the 1970s, handheld electronic calculators transformed the way tens of millions of people did arithmetic. Engineers abandoned slide rules, business people gave up desktop calculating machines, and shoppers replaced simple adding machines and adders.
You're viewing a single thread.
And in 1990, Texas Instruments basically invented the last one as far as education is concerned
Does the TI monopoly extend to other states? Guess I never thought about it before, but was almost excited to see Casio's could potentially be used elsewhere
A TI83 or 84 was mandatory for us to use back when I was in HS in NJ
Yeah I basically ignored my teacher's suggestions and bought an HP instead because I really liked the Reverse Polish Notation it defaults to. I could do everything the TI could do and in fewer key presses. Took some learning though. Had the side benefit that no one would ever want to borrow it because they couldn't even do 1 + 1 in RPN.
TI-85 for me and most of my classmates. Years under us used 82's, IIRC. My buddy had a ginormous TI-92, though.
Delaware checking I'm we basically had the TI 83 or TI-84
It extends all the way to europe, TI-84's were a must and still are. They sell that relic for around €100 still.
Yeah before that I heard they were using trumpets to do their math
I felt like such a rebel with my Casio in high school. It was so much faster, had a better screen, and had way more features.
They still cost about the same now as when I got mine in the late 90s
