ti-83

A now outdated but still useful graphing calculator. Cannot be purchased anymore, replaced with ti-83+. Commonly used to play games in class or cheat on tests by typing in your notes (you know you did). Less powerful than ti-89 but quite perfect for High School use.

So I typed up my notes on my ti-83 last night. Want a copy?

TI-89 titanium

A device that qualifies colleges for free stuff: By stating that students are required to purchase the TI-89 Titanium on their syllabi, colleges are qualified for free equipment and emulator software from Texas Instruments. (from department minutes)

This device is so remarkable that some students can ace a math class with it, but without it cannot add 1/2 + 1/3.

Dean's secretary: Hey, you didn't put on your syllabus that you require the TI-89 Titanium.

(Dean walks in.)
Instructor: That's right. Doesn't it seem unethical to require students to pay $150 or more for a calculator so the college gets free stuff?

Dean: No, not at all.
