Texas Instruments TI-83 Plus Programmable Graphing Calculator (Packaging and Colors May Vary)

Perfect, great condition. battery life is good. Teen daughter needed for school. Works great.

Works great

A little scuffed on the protective case from previous use but it works great.

Easy to use, a bit hard to master. Lots of reading and learning if you want to put apps and program it. Ultimately worth it. Doesn’t come with the usb cable to connect to your PC though which is a bit of a shame.

You would think calculators would get better after being on the market for decades, but there is a limit to their capabilities as exam makers don't want you having a super computer in the palm of your hand when taking tests these days. I really thought I'd seen the last of this calculator in high school, but alas, it's required for University. The TI-83 is an old model and still a reliable calculator. Its use in classes is mainly for its graphing abilities, and it does that fine. However, why does it *still* cost a darn load of money? Because, the manufacturer claims that they don't make the parts anymore, but they can make it—at a high cost. Whatever that means. If you were still mass producing this, you would think the laws of economy would go into effect and this would get cheaper. Apparently, not. This calculator does what it does and if you need a graphing calculator, the TI-83 is the best model to use because of its simple and elegant design, and its sturdiness. Make sure you take out the batteries when it's not in use so it doesn't spill acid inside and ruin your purchase. Once you use it for your classes, you probably won't need it again, and you can sell it back on Amazon. Recommended.

La diferencia en la caalidad tanto en el teclaod como en la sensación de introducción de valores, en que se nota al tacto que el valor entró al proceso. Más facil de ver, caracteres tanto en negro como en amarillo muy legibles, Tan buena como la que compré en 1974 directo desde Texas Instrument cuando trabajaba en CTIO para AURA Inc. Sin duda una buena inversión, la recomiendo. No pude aprender RPN que usa p usaba HP, que es aun mejor pero ni incomparablemente mejor.

ordered for class and works perfect!

I used this calculator for my College Algebra class and it was a lifesaver. There are a bunch of tips and tricks out there that you can Google to learn how to use this calculator most efficiently. The user manual, if you get one, is pretty informative but kinda dry and hard to follow. There are a lot of YouTube videos that can show you how to enter simple programs to find the distance between two points, and the factors of a polynomial. The one thing I didn't like is how the calculator handles logarithms. Perhaps it's just my simple understanding but you can't enter logarithms as they are written, Log(sub 2)7 must be entered as log(7) divided by log(2) Enter for answers. It's not that complicated, but it took me a little while to figure this one out. Otherwise, it's a great calculator, the graphing function can be a little slow sometimes, but having a little patience seems to help. Definitely a must need for College Algebra and I'm sure for higher math classes.

Got this last week and it's in excellent condition.It was a great buy.

En kenap funkar nästan!
