Texas Instruments TI-36X Pro Engineering/Scientific Calculator | 9.7 Inch | Black.

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 hasnt 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-89s treatment of complex numbers without having to deal with different modes (square root of -1 = i without going to any different modes), but it isnt 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 isnt 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 isnt 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 kids 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 arent 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 dont 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. Its not going to come apart in a backpack. To sum it up, Id 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

Ive owned everything from a free calculator that doubles as a pencil case to the TI-NSpire CX CAS with a color display. Aside from graphing, of course, this 36X does EVERYTHING better than any other calculator Ive used. The interface is incredible (fraction bars, scroll and multiple line functionality), it handles complex numbers like a champ, basic equation solving, even derivatives and integrals? So small but SO powerful. Just buy one.

Originally bought a TI-89 Titanium and a TI-nspire CX 2 (Both with CAS) for school. Although it did everything and looked spiffy, 75%-90% of my classes didnt allow us to use it (apparently the CAS and other features do everything for you, who knew?). Once into my sophomore year (this year), something called COVID has placed most classes online making difficult to exclude those spiffy calculators. Any way we were told even though we may WANT to use the nspires and 89s, we need to get used to the calculators allowed on the FE exam. Enter the TI-36X Pro. This thing does just about every thing the spiffy ones can do, but still looks like those old solar powered ones you used to punch 58008 and tell someone to read upside down. Except this little bastard is powerful! Integrals, derivatives, vectors (dot and cross function in the vector menu, no need to write up a matrix and remember that ridiculous formula), solver, system solver for multi variables. This thing can do some serious damage even on a calc 3 exam, and its solar powered so you dont need to remember to charge it or bring spare batteries. Obviously the other beast calcs can graph and this cant. Other than that this thing is incredible for its price!!!! The only downside I would say is that it looks intimidating to use, and has a SLIGHT learning curve to it. BUT if you are going into a Science field and cant learn to use this, then you need to change your major ASAP!!! HIGHLY recommend getting this calculator for any college freshmen that will be majoring in Engineering, perfect for the student budget, and still can whoop some ass.

As a college student who does high-level math, I can tell you that this is the only calculator you need. Why pay 120$ for a graphing calculator when there are countless websites that will do the exact same this for free (i.e. desmos.com) with half the fuss associated with operating a TI-Inspire? This calculator is FAST and EASY TO USE. It is extremely well-designed so that the buttons you need for squaring and taking square roots are really well-placed and the history of previous calculations is very easy to access (similar to a TI-inspire), making using this calculator a BREEZE. Its solar-powered and super durable--Ive had it for 5 years and its never failed me. I dont think Ive ever gotten more worth out of anything than I have this calculator; it had made math easier and more fluid, which is an outstanding feat! Ive never written an amazon review before but I was using this calculator for some homework just now and was overcome by a wave of gratitude about how nice this calculator is and felt compelled to write a review. Please dont buy a TI-inspire.

I love this calculator!!! Ive 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, Avogadros 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 cant beat it!! I noticed one person gave it 2 stars. Let me just say, out of the 15 Ive 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!!!

Satisfactory

I’m in pre cal and my professor won’t allow us to use graphing calculators, so I’ve looked around at several different scientific calculators and While there are a ton of features the pro should have, overall it does include everything you need plus a few enhancement tools, like the solver, and it’s ability to provide exact and irrational answers. Although the pro is hands down the best scientific calculator on the market, it could definitely use some upgrades to make life easier. 1. I wish it allowed you to create a table for more than one function at a time for comparison purposes. 2. Formula memory!! Why does this only have one formula memory slot? (FYI there is a scientific calculator from Sharp that allows you to store up to 4 formulas but it doesn’t have a table mode.) 3. QR codes. I came across the Casio class wiz scientific calculator and it lets you generate a qr code from a table you created and view its graph from your phone. It also has a spreadsheet function. Only didn’t buy because it erases your work once it turns off. I love that you can turn off the TI 36xpro and when you turn it back on again, all your calculations are still there. 4) >,=, and < signs. When I’m making tables, sometimes I only want to see results within a specific range so being able to tell the calculator you’re only looking for values within a desired range would be significantly helpful!

This Calculator is good over all, highly recommend for students that are taking pre-cal or cal. This product came in un-use brand new, the package and everything was sealed but I notices that the buttons are a little shifted. The buttons are a little tipped over and some are shifted downwards

It’s a really good calculator. There is certain equations that it can not do. But over all it had most of the functions and keys you need

As a current highschooler I needed a calculator. Of course this is possibly the most common one around and for good reason. It’s very easy to use and I haven’t had any problems with using one. Very worth it
