Review: Save money!! - This was my first time buying anything used off of desertcart but I needed this calculator and wanted to save money. It came in really good condition, & is definitely worth paying for since it’s literally a steal compared to $100. You do have to put in 4 AAA batteries so just be aware of that. You can tell it’s obviously not BRAND NEW but it’s close enough & gets the job done so that’s all that matters.
Review: Came early, very reliable for high school/ college level courses - Arrived early and is perfect for college math algebra, calculus and engineering classes! Screen isn’t led, but it’s bright enough for use in well lit environment. This calculator is very reliable and comes with pre-installed apps that teach you different math skills and is able to solve equations with missing variables. It is a bigger calculator, but worth it! Only comes in one color black, grey and white which is okay, but it also came with 4 triple A batteries and the usb cord.

## Questions & Answers

**Q: COMPARE WITH  I-83**
A: It's a lot easier to use. The TI-83 requires the user to remember a lot more. It uses parentheticals to enter data, so the user must enter the required data in the required order, but there is no prompt. The TI-84 gives prompts for required data points such as mean, median, z-scores, critical values, etc. It also has more data packages than the 83, so less work has to be done manually. I'm kind of glad my 83 crapped out so I had to replace it! :-P Hope that helps.

**Q: Can this be used for Algebra through Calculus in high school?**
A: Yes it can. Many of my customers are high school / college students. They mainly use it for calculus and statistics all throughout their school career.

**Q: Is this allowed for sat/act tests?**
A: This is allowed on both the SAT and ACT tests as well as AP exams.

**Q: will this calculator fit the needs for all math? (calc, algebra, geometry, etc...)**
A: is this good for high school geometry
