The best thing:
-you can enter entire expressions and solve them. this is because, unlike earlier models, functions like sine, cosine, tangent, square root, etc. are entered before the number. for example, with other models you would punch in 45 and hit tan, and it would automatically give you the answer 1. With the 30XIIS, however, you press tan, then 1, then enter. It seems like a disadvantage at first, but when you are doing more complicated math and need to enter a whole line of info, it's a huge time-saver.
Other good things:
-You can go back and substitute other numbers into your expression. This is great when you are doing guess-and-check work, but it was most useful in chemistry and physics, when I had to use the same formula with a lot of different values. I was really bummed to discover the graphing calculators didn't have the ability to go back to an expression you've already solved.
-The buttons are arranged really logically. There were about three buttons grouped together up in the corner that I never used (I think they're maybe for statistics), but they were totally out of the way. When you're doing trig, all the buttons you need are near each other. Same with logs and everything else. After using this calculator for a while, you can key things in so fast. Hitting 2nd [ans] is like a reflex now.Read more ›
I remember entering algebra in K-12 hearing "you'll need a TI-83+ graphing calculator"... oh my, what a lie! Honestly, this is all you will ever need if you're not going above and beyond calculus. Using a graphing calculator is also horrible practise for introducing algebraic concepts. Keep it simple and you'll learn more, not that this is necessarily a "simple" calculator! The main thing you won't have is graphing, the less important chapters of algebra to boot. Besides, how hard is it to plot a few points on a coordinate plane and draw lines? Things like polynomials you should be able to do with ease, unless you're one of those procrastinating/lazy types who could care less. I suppose if it's all too excruciating, spend the extra $50 and cheat yourself.
The only thing that caught me off guard was that my TI-30 cover is a dark blue instead of black, but I'm hardly complaining! Minus 0.1 star, but 4.9 stars rounds to 5.
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 [...] for a good overview of TI calculators, and you can scope out one of TI's major competitors at [...]
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.
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.Read more ›
