TI-84 PLUS: Algebra 2

This week in Algebra II, we've been learning how to put our points, ((x,y)), in a graph. You have to press a million buttons to get your outcome and it's very complicated. Even I'm still getting the hang of it.

We've been working on the line of best fit, and trust me, it ain't easy. When you put in your coordinates, you have to press at least six or seven buttons to get your output. After you push the buttons, you have to press more to find your final answer. So many buttons for one little problem!

You have to be sure and use them correctly; otherwise you'll get some far off number. Make sure that your x's and y's are plugged in properly. I got lost on what buttons to push and what uttons were meant to be pushed and when you pushed them.

Thankfully, Mrs.Waldrop, the teacher, made sure that we all knew what we were doing before we left and how to work the calculators. Practice makes perfect. And this will take a lot of perfecting to work these calculators.

When you try to use a TI-84 Plus calculator, make sure that you practice it with a classmate, teacher, or other people that know what the heck they are doing with the calculator!!
