### How old is the TI-84?

The TI-84 Plus is a graphing calculator made by Texas Instruments which was released in early 2004.

**Do I really need a graphing calculator?**

Many schools prefer if students have their own handheld scientific calculator. In the highest level math classes, like AP Calculus, a graphing calculator may be required. A graphing calculator does even more. It will have a larger screen that allows you to type in a function, then see a graph of it.

#### Do kids still use TI 83?

Technology has not yet killed the reliable old TI-83. Nearly 20 years later, students are still forced to use a prohibitively expensive piece of outdated technology. It’s not because better tools aren’t available; they exist, and some of them are even free.

#### Can you use a TI 84 on the ACT?
