T-84

The TI-84 is a fancy calculator that can do big math problems for you, like when you have to do a lot of adding, subtracting, multiplying or dividing. It also has some cool features, like graphs and tables that can help you understand what your math means.

Think of it like a brainy friend that can solve really tough math problems, but also likes to show you pictures and graphs to help you understand what's going on. Just like how your friend might show you a picture to help explain a story, the TI-84 can show you a graph to help explain the math problem you're trying to solve.

So if you ever have to do some really big math problems, or if you want to understand what the math is saying better, the TI-84 can help you out!
