Texas Instruments Quality, Light Weight, Reasonable Price
I bought this calculator when my old machine shop calculator died from being dropped too many times. There are a few things to note about this calculator for this type of calculation. And since I'm a retired mathematics teacher, I know a thing or two about calculators in education. First, this seems like a great choice for use in a machine shop. I need a high quality and durable calculator with trigonometric functions. This calculator is all that and more. The multi-line display is also convenient for seeing a record of previous keystrokes. Its quite a bit lighter than the old graphing calculator I was using, and I'm hoping that will make it more durable--lighter objects hit the floor with less force than heavier ones. This calculator has enough capability for educational use IF you don't need (or are not allowed to use) graphing or computer algebra functions. It is not a graphing calculator. And it won't do computer algebra operations such as solving equations, computing derivatives, etc. It's probably not the best choice for linear algebra (matrices, vectors, ...) or for advanced statistics. But it does have all the numerical functions you would expect to find in a classic scientific calculator. Last note is that this calculator has a snap-on lid instead of the old slide-on style I'm accustomed to (like on the TI-84). It's too early to say whether I like it more or less. Its definitely faster: just clip it on or off. But will it hang-on or survive as well as the old slide-on style if you occasionally drop it on a concrete floor? ... show more

I love this calculator!!! I've had it since Sept/2011. Before this calculator I had the TI-89 and loved how it could do anything I could want it to do. With knowing that I would be unable to use this calculator on the FE, I decided to buy one that they would allow so I would be use to it before the exam. I originally took the advice of a friend and went with a the Casio 115es. Being that I have had Ti products my whole life this was a huge learning curve. The calculator was nice but was not that user friendly! (almost felt like I needed a minor in programming to work it!) I was told that it would solve for variables but never could actually learn how to get it to do it. One day a friend in class showed me his Ti-36x pro and I was amazed at how easy it was to use! It did alot more then the Casio and was almost like having my Ti-89 back!! To be honest its easier then the 89 to operate and still solves for variables (along with alot of the other same functions). I have showed mine to my fellow classmates and they also fell in love with it. They always end up having me order them one. So far I have ordered 15 of these calculators and have not had one complaint out of any of them. I have tried almost all calculators allowed on the FE and this one is far ahead of the pack!!! Some Pros: The Biggest Pro is: Its pretty user friendly after you get sometime on it The ability to scroll through old computations See math expressions, symbols and stacked fractions exactly the way they appear in textbooks. Has nine physical constants programmed into it (like:Gravity, Speed of Light, Avogadro's number, Ideal Gas Constant..) Has 18 Metric/English conversions Does integration and derivatives Gives you answers in decimals by default (unlike the Casio) but will convert to fractions If you turn it off and back on it still has your old calculations! (the Casio erases when it turns off!) If you are a TI user, you can easily adapt to this calculator. For the price you can't beat it!! I noticed one person gave it 2 stars. Let me just say, out of the 15 I've ordered for people, I have yet to have one complaint!!! Cons NONE!!! If you are not allow to use a graphing calculator in your classes or you will be taking the FE one day, I recommend this calculator. It blows any other Scientific Calculator out the water!!! ... show more

Great Engineering Calc, FE approved
The absolute best choice of calculator for an engineering student. It is highly intuitive and doesnt' require referencing a manual four hours to figure everything out. All of the main functionlity is right there on the front in easy to locate buttons, and the menus are easy to navigate. FE Exam approved calculator with lots of memory for referencing prior calculations. Highly recommend! ... show more

Well thought out and a powerhouse!
What an improvement over my old TI scientific calculator I've been using since the 90s. All of the functions on this unit are intuitive and it's easy to navigate through all the menus. Remember the math key, it is your friend! There's a lot of sub menus that contain more functions than what are printed on the face of the calculator. This is a great calculator for electrical engineering and for general calculus. It will be seeing a lot of use in my electronics lab! ... show more

Should have been released earlier!
TI-36X Pro calculator (A non-graphing scientific calculator) I originally reviewed a TI-30XS Multi-View and a Casio FX-115ES when I took the Professional Engineer exam because they were the only ones available at the time that I could use without too much difficulty. I took 3-4 months before the exam to familiarize myself with the calculator before I took the actual exam. I felt the Casio FX-115ES was far superior, although the TI-30XS MV had a much cleaner interface and a sensible layout. But the FX-115ES was very easy to use once you got used to the menu/layout as Casio hasn't changed its scientific calculators very much over the years. Many of the features I favored in the FX-115ES were not available in the TI-30XS MV such as complex numbers and handling matrices, and even working with different base numbers. The TI-36X Pro seems to have resolved many, if not all, of the TI-30XS MV shortcomings. Had the 36X Pro been available in late 2008, I would have most likely used it for the exam along with my FX-115ES as a backup calculator. The 36X Pro interface/layout is similar to the TI-30XS MV which makes it easy to use. The answers default in approximations (decimals) versus exact numbers (fractions) with the FX-115ES. This makes it easier for engineers since I always had to press the convert key on the FX-115ES. The TI-36X Pro treats complex numbers the same way as the FX-115ES, just make sure to set it in the Complex mode for polar or rectangular values. I still prefer the TI-89's treatment of complex numbers without having to deal with different modes (square root of -1 = i without going to any different modes), but it isn't too hard to change a few settings in the 36X Pro and it even has a key for i albeit it is a multi-tap key, but it works in the REAL mode. Different number bases with the 36XP Pro require navigating more menu layers versus the FX-115ES. With the Casio, you could directly switch between DEC, HEX, BIN, etc... whereas the TI 36X Pro requires you to convert the values. Again, this isn't a big deal it is just a matter of a few extra seconds of time. The TI 36X Pro has a better menu, but the FX-115ES is more direct. I guess that is probably a Japanese trait as well! The TI-36X Pro has lots of conversions and constants, and they are actually described in the menu which makes it very easy to use versus the cryptic FX-115ES. Again, the FX-115ES can be more direct - but that is the same for Microsoft DOS or Unix. They can be very quick and direct, but no one wants to use cryptic commands. A GUI or touch-screen is far more intuitive and that is where the TI-36X Pro shines. However, the TI-36X Pro conversions are very basic and limited to some common conversions. For exams, this isn't as big of a problem. For scientific or engineering work, I would prefer more conversions available on the spot. The multi-tap keys on the 36X Pro are an excellent idea. TI probably had to do this because they ran out of room for more buttons or a "3rd" key. The multi-tap keys are easy to use, just repeatedly press them until you get the command you want. The color scheme of the calculator itself is an improvement over the TI-30XS MV. The 30 was white with a teal/blue green color. The white has now turned yellow, and the 30 always looked like a kid's calculator. The TI-36X Pro is a black/dark gray motif and there are 7 keys coated with a metallic color. It makes it hard to read the symbols, but TI did etch the 6 keys with their commands. My only guess as to why they did this was that the keys tend to rub smooth with repeated use. I had my TI-86 for the longest time since 1996, and most of the keys were polished smooth by the time it started to malfunction and use up batteries in a few days. So the etching/molded keys aren't a bad idea - I just wish they used a more visible/contrasting scheme for those keys. The solar assist comes in handy for exams because you don't have to worry about changing your batteries too often. Although TI does mention this is just a solar assist to lengthen the battery life probably by using whatever photovoltaic source you can get via the cell but relying mainly on the CR2032 lithium coin cell. I removed the battery and the calculator refused to turn on even under direct sunlight. So apparently the calculator does run on the CR2032 battery and utilizes some assistance from the solar cells. I am not a big fan of the hard case, as it clips at the bottom and top. I prefer the slide case of the TI graphing calculators although the 30XS/36X Pro case has better retention. It's not going to come apart in a backpack. To sum it up, I'd recommend the TI 36X Pro in situations where you cannot use a graphing calculator. I am still split on the Casio FX-115ES and the TI-36X Pro, although I feel both are on-par in terms of features. The TI-36X Pro is definitely more user friendly. Overall: 4/5 stars ... show more

The best scientific calculator on the market!!
This calculator has helped me tremendously throughout my college experiences so far. Spanning from elementary algebra, all the way to Calculus III. Amazing battery life, Very portable, and has great durability to it. You do need some type of external source of lighting to see the calculations on the display, like a bright or dim light. I highly recommend if your professor(s) doesn’t allow graphing calculators. ;) ... show more

The TI-36X Pro churns out exact answers that graphing calculators won't do.
There are some great reviews for this product, but I have seen the lack of mention of one outstanding thing about this calculator. I haven't owned many calculators, but I have used a Ti84 Plus and a Ti84 Plus CE for many years through high-school and college. Albeit this calculator is not a graphing calculator it performs very well and meets my expectations for engineering courses. In fact something stands out. This calculator by default does EXACT math! One thing I have never encountered (and long stopped expecting) was putting the square root of 8 in a calculator and getting back a simplified radical (2) X (the square root of 2). The TI Graphing calculators will always give, an irrational number (2.828427.....) If you want to get a simplified exact answer, you better know how to program or download from the internet an app for it. With the TI-36X Pro, you put it in and it churns out your simplified radical (even rationalizing the denominator of a fraction), every time, not only this, it does the same with pi, opting to display the pi symbol with the most simplified fractional form of your answer. Even if you don't want an exact answer, there is an operator key that will give you the decimal approximation if you desire. This would have been very convenient in classes I took, such as Calculus 2 and 3. Where during a test or on homework, you are often left with very long strings of numbers you have to use add/subtract - multiply/divide. Most teachers want you to give an exact answer so you can't just throw it all into a Graphing calculator, it will give you an approximated number. The TI-36X Pro, will take all of this math and give you a perfectly simplified and exact answer. A $30 dollar calculator capable of something my $150 dollar calculators don't do. ... show more
