Reliable Calculator for High School Math
Perfect for advanced algebra and geometry, it works. Easy to use, durable, and a fair price for the quality. I bought one for home and another for school so my teen always has one on hand. Great value and reliable performance.

Buy for school!
Came in good quality, reasonable size and it is a good calculator for high school and college algebra, even chemistry workings. It takes a while to get the hang of how to use it but once you do, you’ll be passing all your tests!

For under twenty bucks, this thing delivers every time. Think of it as the Honda Civic of calculators — dependable, affordable, and built to last.Bottom line: If you need one, stop overthinking it and hit “buy.”

Great Value for a Reliable Scientific Calculator
The TI-30XIIS is a solid, no-frills calculator that gets the job done for a great price. I’ve used it for everything from high school math to college-level science courses, and it’s never let me down. The dual power (solar and battery) is a nice touch, and the two-line display makes it easy to review your inputs and results.It’s not flashy, but it’s dependable, easy to use, and approved for most standardized tests. For the price, you really can’t go wrong. Whether you’re a student or just need a reliable calculator for everyday use, this one’s a smart buy.

great calculator
I would rate this calculator maybe a 6,7 out of five;) Most of the time I use it I get a 100 (but when I don’t that’s my fault. ) Its batteries have lasted all year so far ( a little over a quarter) and I use it pretty much every day so that’s good. It fits in my 98 cent pencil holder from Walmart so you don’t have to buy a super expensive one but I doubt that even crossed your mind but oh well. It’s also really easy to use even though I don’t know what half the buttons mean so that’s nice. It’s also really good quality and it has this nice protective cover that I don’t know what it needs protection from unless you leave it out in the woods and a bear needs it to do his math homework with it but at that point you probably have better sense than to steal your calculator from a bear cuz at that point just buy a new one because you don’t want to risk your life trying to get your calculator from a bear plus that’s probably not the calculator’s fault and no reason not to buy it and I really doubt that that’s gonna happen because bears don’t even do math homework. so yeah ,’:)

Excellent calculator for college
I got this for my daughter’s college math class. It was recommended by the instructor. She loves it and it has all the functions she needs to help complete her assignments. The price was also reasonable.

The best Texas Instruments calculator you can buy.
Probably the best way to spend $15. Durable, easy to use, battery still holds.

The calculator did not arrive in the original packaging done by TI. It was bubble wrapped with the original documents. When I turned on the calculator and checked the history, it was clear that this piece was used. It is not worth to buy a used piece for €27.99.

Per calcolare un logaritmo ci mette quasi un secondo o forse un secondo intero! Non l’avrei mai scambiata con la mia altra calcolatrice che rispetto a questa era cento volte più veloce, ma il mio master non permetteva usare altre marche. Uno spreco di soldi! Evitatela.
