Texas Instruments TI-30XIIS Scientific Calculator, Black

I bought this calculator for my son, who is in high school. The calculator is a slim design, durable (it's been knocked off his desk a few times), and it can withstand being carried around in a bag with heavy books. The actual calculator is easy to use, powers on as soon as he slides the cover off, and the buttons do not stick. We bought this as a replacement for another brand that was more fragile, and the buttons would stick and therefore give inaccurate results. We bought this exact same calculator for my oldest child, and he used it all throughout high school and college. A great buy for the money!

Purchase this for my middle school student. It has all the functions required for his math class and the battery last quite a while before needing to be recharged. Everything functions well with buttons that are easy to press, clear and stores perfectly in his backpack without taking up a ton of space. Purchase this for my middle school student.

I got it for grandson's 8th grade math.

Cheap and efficient for my middle school kid

I bought this for my husband. He uses it at work and is very pleased with it. :)

I always buy these calculators for my students in Gr 9-11 Math to purchase from the school. They are great, easy to use and have all the necessary functions. Love the 2 line output so students can see what they entered as well as the answer.

Nice features on a simple calculator. I really prefer one that uses reverse Polish notation but they are now rare and expensive.

All I wanted was simple math, but this does so much more; much more than I anticipated.

I am a grade 10 student, and we needed a scientific calculator for math class. The school has some of these floating around, and our teacher recommended these over Sharp name brand because this has all of the functions that we basically need, and at the same time, they are very easy to function and see what you are doing because there is a 2 line display, which is nice because sometimes if you make a mistake putting in the numbers, then you will get the wrong answer, so this way, at least you can confirm before writing your answer and then noticing it is all wrong and having to redo it all over again. This calculator has become my new best friend in math class! What happens when the battery dies on the one I bought (although it runs on battery and solar, which is nice)? Well, I would try changing the battery first, and if it still won't work, I would still want to buy the same one because it is so easy to use and you get used to working it, and when I try using another different one (like Sharp,etc), I do not know how to work it. Would I recommend this model to a friend? YES, I ABSOLUTELY WOULD! Thanks Texas Instruments for making such a great calculator!

Very easy and simple to use.has a lot of features for a lower price .
