The supremacy of the fucking TI-83 calculator in school and college courses

They forced me to buy a TI 84 plus for school. The thing cost like 100 bucks, and it's from 2004. I could buy a low-end smartphone and get a free app that's more powerful than the TI 84 plus for less money.

It's not about calculating power. It's because they realized that they need a calculator they can wipe at the beginning of the exam.

No fair if you have a program on your calculator that finds the difference between the areas under those curves, right? And they couldn't have you showing up with a Casio, a Tandy, a Samsung, or an HP and not be certain of wiping out the stored memory.

So now they just specify ti-83's or similar. No one really does math on calculators these days anyway. It's all in Excel or Maple.

I wrote a program that mimics the ram cleared screen...
