Customer Review: Best Value for Your Money
Summary: 5 Stars
Definetely a best value for the price paid. Highly recommended.Customer Review: 4 1/2 Durable and Inexpensive!
Summary: 4 Stars
Main Points:
I used this calculator for over 10 years before it finally stopped working, and I treated it fairly roughly (e.g.,coffe spills). I think others here have attested to the functionality of the TI-30, so I just want to emphasize that it's a tough little gadget as well. Yes, the buttons are on the small side and there is a bit of play, but this was never a major problem (although at times it slows down data entry). You can go to http://education.ti.com/downloads for a good overview of TI calculators, and you can scope out one of TI's major competitors at http://www.casio.com.
A Little History:
This was also one of the first commercially available low-priced calculators that had two-line display and backspace to correct or edit data entry. The dual-power and scrolling display features were also once unusual. The top line (for data entry) shows up to 11 characters; you can scroll backwards or forwards up to 88! The bottom line (shows results) displays up to a 10-digit answer along with a 2-digit exponent.
Individual Needs Differ:
From the reviews here, it appears that high school math is now more difficult than it once was. If you know that you're going to need graphing capability, then obviously this is not the choice for you. Similarly, the prevalence of laptop computers and math/stats software may obviate the need for some of the more advanced features.
Recommendation:
The layout is very good and, for such a low price, it packs a lot of calculating might. However, high school (or college)students may want to narrow their choices and then ask their teacher which one has the most relevant functions for the next few years of math. Compared to twenty-five or so years ago, one can now get a lot more calculator for the money. Depending on your budget, therefore, you might determine that a calculator like this is sufficient for your short-term needs, but that you'll need a new one if you go on to more advanced stats and math. In any event, this is a durable calculator that works very well.
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: 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.
