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

Very good product

I got this while taking civil engineering courses and it has been able to do everything Ive needed for those courses. It is a process to learn all the functions, but I think thats expected.

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!!!

I now have two of these calculators along with a Casio and HP. I took it upon myself to try all three leading up to my EIT exam. I almost always reach for the TI-36XPRO. It should be noted that there is a bug in the calculator regarding how it handles mixed fractions. Ive never considered this an issue for me personally because I calculate everything to a desired amount of decimal values. Even with the bug I consider this calculator worthy of 4.5 Stars. It is still very odd that TI hasnt attempted to address this issue with newer makes or models. I rounded up to 5 instead of giving it 4 stars. The multi-tap functions can seem tedious at first but consider that youll almost never have to dig through the calculators menus for most of your functions. The pros over the Casio are the multi tap and clearer button layouts and button prints. The Casio button layout and print are frustrating to even look at at. The same goes for the HP. This calculator is at par with the HP except it doesnt require the RPN learning curve which can be significant for some. I see the RPN debate as this...RPN observes order of operation which is the way you calculate. The Ti 36 and Casio inputs are linear which is similar to the way you write. You might write 10 lines of math for every couple of calculator calculations which means the linear input is probably more common and easier for your brain to input initially. A linear input calculator doesnt stop you from inputting calculations according to order of operation either which is where linear input calculators are better than RPN. With RPN you stuck to one input logic. The final Pro for this calculator is cost. I have two of these and will order a third one soon. All three calculators should cost me the same as one HP.

It came delivered nicely and the packaging for the item made the item feel really new. This has helped me in my math class!

Let me start by saying Ive been using the TI-84 plus CE calculator for 7 years now. However, as a civil engineering student in university, Im not allowed to use that calculator in my classes or on my exams because it has too many features that does the work for me. I also cannot use it for my FE or PE exams when I want to get certified as an engineer. So I had to downgrade and buy this one. If youre a civil engineering major, this is the next best calculator thats FE/PE certified. It has the most features and its the most similar to the newer calculator versions. After being so familiar with a calculator for 7 years, its hard to switch to another one. But it only took me a minute or two of fiddling around with the 36-X PRO before I got the hang of the different buttons and command locations. I also LOVE that I dont have to worry about charging it! I cant count the amount of times I would sit down in class or at home and take out my 84 plus CE for an assignment or homework and it would be out of battery. It was such a pain to remember to charge it. Note: Even if youre not an engineering major, and youre just in high school or college, get this calculator! I started using my TI-84 plus CE in 8th grade and these types of calculators are a lifesaver. Itll help you in the long run and save you a lot of time and effort instead of using a scientific calculator. It has so many useful functions can really help you when youre on crunch time in an exam or something like that. 10/10!

I bought this calculator for my upcoming FE Exam in October 2013. I have been using it for the past couple of months to get acquainted and to study. When I was in school I used the TI-89 Titanium religiously. Unfortunately thats not permitted on the FE exam so I chose this one. Upon using it I must say that for a non-graphic calculator its fantastic. The shortcut keys (for exponents, powers of 10, fractions, etc.) are a nice touch. The built in equation solver, polynomial equation solver, system of equation solver certainly shave a lot of time off of my calculations concerning static equilibrium, quadratic equations and circuits. This calculator also does Matrices, up to 3x3 and vectors in three dimensions. It even has popular constants (permittivity, Boltzmann, Ideal Gas, standard atm, etc) built in along with a whole conversion menu. On top of that it does numerical integration and numerical derivatives and plenty of other things Im probably not going to mention. I consider it to be more user friendly than the TI-89 Titanium because of the shortcut keys and nice interface. For example, to calculate a determinant on the TI-89 you must press 2nd, MATH then scroll to Matrix, then select Det( and press enter. Then you have to remember the syntax which is det([a1, a2, a3][b1, b2, b3][c1, c2, c3]) and finally press enter. On the Ti-36X Pro all you have to do is press 2nd, Matrix and scroll to edit and enter how many columns and rows you want in the specified matrix, press enter and then put in your values. Then once the values are saved you go back to the Matrix menu and select Determinant and put in the name of the matrix where you saved the information. Pretty slick for a smaller calculator. The four line display provides enough room to see what your doing and the text is fairly large which I like. With the bigger calculators you usually have to squint to see some numbers, especially in low-light situations. This calculator also features Mathprint. This means that fractions, integrals and most other mathematical notation shows up as its supposed to. However if you dont like this there is a feature to turn it off. This is especially useful for when youre calculating something like a parallel resistance circuit and you want to see that big fraction to make sure you didnt make a mistake. Of course no review is complete without listing the gripes. Theres not too many problems with this calculator however there are something that really bug me. The first one being that there is no option to toggle insert like the TI-89 has. Usually I find myself needed to edit an equation that I just entered. Therefore I have to press second, then insert and put whatever I needed into the equation. Not a big deal but can get annoying at times. Second, I dont like the chrome arithmetic buttons. At times I find myself hitting the subtract button when I wanted to do some addition. However I solved this problem by running a fine-tipped sharpie over the buttons and rubbing off the excess on the surface. Now the symbols have a black color in contrast with the chrome. Much easier to see and I suggest this method if anyone else has this problem. Third, you must press a button multiple times to get what you need. For example say I want to type a complex number (3+5i) on the screen. I press 3, +, 5 and then I have to press the pi, e, i key three times just to get the i symbol. Can be a bit annoying/frustrating and you might make a mistake if youve had way too much caffeine as I normally do. Although I suppose they had to do this to consolidate space in the design process so I can respect that. Just a little annoying but I guess it comes with the territory. This can add a bit of time to the learning curve if youre not used to these multipress buttons. Thats basically it. For a non-graphing calculator I give it a 9/10. Comparing budget calculators, Ive had the TI-30Xa and the Ti-30XIIS before and this one blows them out of the water obviously, hence the name TI-36X PRO. Ive never had a Casio calculator so I cant compare. With this many features and usability at the price of $17 or so its certainly an exemplary buy. A great budget engineering calculator and certainly the best to use on the FE exam in my opinion. Go with this one!

The calculator is very good overall. My only complaints are with things such as decimal to degrees/mins/seconds and vica versa. You have to navigate a bunch of menus to this basic conversion. It is actually faster to simple divide by 60 then 3600 to find the mins and seconds then to navigate the menus. The calculator suffers from not having a simply button to convert back and forth. Like a dec -> DMS button would be a huge welcome. Especially since this calculator is primarily used on the EIT/PE and LSIT/PLS exams.

This calculator was an upgrade from my son’s middle school one (TI-30xiis). I was looking for something that would carry him into advanced math and even college maths, without being a full-functioning expensive graphing calculator. So far, straight out of the package, I can already see that it was a good choice to upgrade. It has more functions, a user guide cheat sheet in the lid, rubberized grips both on the calculator and lid, a larger display screen, and more. The function buttons are NOT metallic as shown and mentioned in older reviews. See pics.

I hate math with a passion, but I am so glad I have this calculator.
