Customer Review: Fantastic! Don't buy a graphing calculator!
Summary: 5 Stars
Working towards BS in physics; after years of using my TI-86 I figured it'd be rational to get a solar backup just in case I was ever in a jam for an exam. Not needing something exceptional (yet) like a TI-89 or one with graphing capabilities (that I'd actually use), I settled on this bargain calculator. After I tried it out, I did some reflection and felt absolutely disgusted that I wasted ~$100 on my TI-86 when I could've gotten all I needed for <$20, and of course by "need" I'm pointing towards saving time on simple time-consuming math. This calculator, meant to be my backup, replaced my TI-86. It has everything I need, is well laid out and doesn't require batteries.
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.
Customer Review: A Classic is Reborn
Summary: 5 Stars
I purchased my first TI-30 in 1977 and carried in a drop holster with my slide rule, mechnacal pencils, and technical drafting pens. As the years went foward I relied on variant of the TI-30 for the latest, and every few years upgraded as I progressed in my profession.
The TI-30 has been an asset to the engineering business since the days it replaced slide rules as a portable calculator, and even today it remains one of the fastest and easiest pocket calulator to use by an engineer.
The larger beasts such as the TI-89 are fine for heavy lifting and complex transforms, but this variant of the TI-30 family is a superb buy for only a few dollars, and since the solar cell keep the power topped off so you don't have to worry about batteries.
This, and a TI-89 should both be kept on your desk, or in your briefcase. One TI-89 for the heavy lifting, and several TI-30's for the lighter duty number crunching.
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
Summary: 5 Stars
From reading most peoples bad reviews, they seem to want a standard scientific calculator. THIS IS NOT A STANDARD SCIENTIFIC CALCULATOR AND NOT A GRAPHING CALCULATOR.
The purpose of this calculator is to replace your TI-83 or 84 if you can't use a graphing calculator on a test. The idea is that it has the same layout as those graphing calculators. Personally, I love my TI-84 and hate that I can't use it on tests, and I hated practicing to use a standard scientific calculator. One of my friends had this calculator and I borrowed it, tried it for two minutes, and was like "What the hell have I been wasting my time around with other calculators for."
Bottom line: Buy this calculator if you can't use your 84 on a test.
Customer Review: BEST 5 Stars
Trust me on my word. This is the best calculator ever. And if you dont believe me just because i am a kid, well it's your loss. I bought this calculator and i gave it to my older cousin and he is in high school. Then he gave it to me and i am using. If your wondering what a 12 year old is doing with a scientific calculator well i go to HUNTER COLLEGE and it is from the 7th grade to the 12th. This claculator is best for freshman high schoolers and going to college. The only con is the buttons wiggles, but everything else is fine. Buy this calculator for a fine price or you will be sorry. it works from pre algebra to pre-cal and knows trigonometry.
