“I’ve been using a TI-84 for over 12 years! It’s one of my life comforts at this point, no other calculator will do! I love showing student statistics on them! The sorting lists and making histograms are always hits!!”
“I love how easy it is to use a TI and how easy it is to do regression (especially compared to the one my state uses for state testing).”
