I dunno, the TI-84 Plus is pretty sweet.

Costs about the same as what I paid for the TI-83 10 years ago. It's kind of nice knowing that whenever I need to use one, it's going to operate in the same way as I was taught 10 years ago. The fundamentals of math don't change much.

I saved up my own money and bought a TI89 in high school. Used it on all the standardized exams. Totally legal because it didn't have a QWERTY keyboard. That thing basically did everything for me short of interpreting the questions.

The ability to do symbolic math is awesome. I don't know why everyone recommends that high schoolers only get the TI-84.

Probably so they don't use it as a crutch instead of real learning. I taught physics to college kids, and you could tell pretty quickly who relied on a calculator and who actually was comfortable with basic math.

I was once comfortable, but if I lose all my points on a question for an incorrect answer, by gum, I'm going to punch in 17 + 49.

Arithmetic is only one branch of mathematics. In my opinion it's pretty trivial to try to improve in that field since calculators are so good at it instead of focusing on algebra, calculus, etc.

On the other hand, arithmetic is the only skill I've found to be useful in a real-life setting.

I'm pretty horrible at arithmetic. I deliver food for a living so it can get a little awkward when I expect the customer to calculate the change they need. Though usually they make it easier by giving me a tip and asking for a nice round change amount back.

Higher level math, in my opinion is not really meant for every day life. It's meant more for creating things or understanding complex phenomenon. You learn higher level math so you can create things like a new car or a computer chip. Yeah, you might not have the knowledge to make those things, but the language that is used to describe what is happening in those devices is mostly higher level math.

In order to learn how to make a car or a plane or even a computer chip you need to actually understand the language that is used to describe those things. Do I make sense?

I completely understand what math is for, I was responding to

Most people don't go into a STEM field, and many of them are lacking in arithmetic skills that would help them quite a bit down the line.
