Digital Cameras Photo Reviews of Texas Instruments TI-30X IIS 2-Line Scientific Calculator
Customer Review: Great Calculator!
Summary: 4 Stars
I've had this for about 7 years now (from high school to college) and it still works fine! It's small, handy and inexpensive. I like the 2-line display and how you can see the equation as you input the numbers. You can also scroll to previous equations you have entered, sort of like a "history" for your calculator. It's easy to delete numbers in the equation too, if you make a mistake, rather than clearing it and starting all over again.The only problem I have with this calculator is, sure it has a lot of functions but it's difficult to figure them out unless you plan on taking the manual with you all the time. It has cool functions, but it'd be cooler if I knew how to use them all.
Otherwise, good stuff, I highly recommend it, especially if you're just taking basic math/algebra courses that don't need graphing calculators and the works.
Customer Review: It's just okay
Summary: 3 Stars
This is my third Texas Instruments calculator. I also have a TI-84 and a Voyage 200, both of which I love. I bought this one because I needed a no-frills scientific calculator for my Diff Eq class. I didn't have a lot of money to spend, so this one seemed to fit the bill. I wish I had gone to a bricks and mortar store and tried it against some other ones, though. It has all the functions I want, including storing the previous answer, but the buttons don't always register a key press. It is really frustrating to be in the middle of a test and have the calculator get temperamental. It is especially bad when I don't notice it happened and mess up a problem because the button didn't register. It's not an issue with the buttons being difficult to press, either. The button presses just don't get picked up some times.Customer Review: Great, Standard Scientific Calculator
Summary: 5 Stars
When I was taking courses in calculus and physics, I used the TI-86 because it had more functions and was more powerful, for the kind of math that was needed.
However, the TI30XIIS is an excellent scientific calculator. It has most of the functions of a scientific calculator, with the scrollable screen that lets you check your numbers before multiplying, and perform many operations using the "Ans" function. As an organic chemist, it's the only calculator I need when it comes to doing simple chemistry calculations, which involve a lot of basic operations.
If you need to do derivates, integrals, polynomials, etc, then you should get something more powerful. If you just want a calculator to do your basic math yet allow you to check your numbers with ease, then this is a great calculator to have.
Customer Review: TI 30X IIS
Summary: 4 Stars
This calculator seems to be a good scientific calculator. Unfortunately, it was not what I needed. I had a TI 30X-A that was about 20 years old. I loved it, but alas, it died. When I went to replace, I could see the benefits of a two line calculator. I liked the idea of dual power.
However, since I mainly use it for accounting purposes, this calculator does not work for me. I went through the manual looking for a way to make it work, but found none. I use this for check books and other things where I need a running total. IE. with this calculator, if you wish to enter 1+2+3+4 with a subtotal and then a total, you have to hit 1+2=+3=+4= to get an answers. So I am saving this calculator for my preteen who will need ti soon enough and I went and bought another trusty TI-30XA.
Customer Review: Missing commas as separators
Summary: 4 Stars
I have the TI 30X-IIS, a nice dual power, 2 line calculator. It has one feature missing, the fraction bar key, that another TI has. Other than that, pretty much the perfect machine for me... except it does not use a comma in numbers to separate the thousands place: it displays ten-thousand as 10000 instead of my preference 10,000
I know, most people probably do not care, I must have some kind of dyslexia because when I see 4589339 I have no idea what that is, as compared to 4,589,339 which I instantly recognized as 4 million, 5 hundred thousand,etc.
I'm looking around for another calc, one that has a 2 line display, that works with fractions and decimal conversions, the basic stuff, AND displays numbers with the lil' comma. I would prefer a TI.
