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

I love this calculator. I grew up with a TI-83 Plus and believe the TI-36x Pro is the best one for the FE Exam. I tried the Casio fx-115ES Plus for 9 months, per the advice of an excellent prof (mechanical and civil background), and while it has certain advantages I find the 4 line display on the TI-36x Pro alone is reason enough to use it instead. I can complete complex problems more efficiently and with less errors than with the Casio - it is easier to backtrack, check what was entered before, and select equations/numbers from previous lines to be carried into new calculations. With the Casio I would often accidentally clear the screen with the on button, out of habit, which deletes the previous entries from memory; even when this was not the case I found it difficult (impossible?) to paste prior entries into current calculations. Also, the Casios list of less-common scientific constants must be referenced to a numerical list of symbols (no names given) on the cover, while the TI-36x Pro lists constants with symbols/names spelled out in the menu itself - much more convenient. This calculator can accept up to 3x3 matrices and can solve systems of linear equations with three unknowns using the entry [A]^(-1)[B]. The way it handles complex numbers is also very convenient, allowing for easy conversion between rectangular and polar form. The only major downside Ive discovered so far is, in matrix mode, the TI-36x Pro cannot accept imaginary numbers as inputs. This is true of many other calculators as well (including the Casio fx-115ES Plus). Its problematic when analyzing AC electrical circuits using mesh (KVL) or nodal analysis (KCL). [Update: The TI-89 Titanium can handle these complex systems with cSolve (but is not FE approved).] One annoying aspect: there is only one button for storing answers as variables, so if you want your entry to be stored as anything other than x, you have to press the variable button repeatedly until the desired letter shows up (for example, for b, you have to press the button 6 times, which cycles x > y > z > t > a > b). [Update: Discovered 2nd -> Recall lists all variables - much faster for recalling them than cycling is. As far as I can tell, however, first-time storage (###->var) does require cycling as stated above.] This is only a minor qualm though; the overall benefits of this calculator easily outweigh the few negative aspects.

Have use it for math test, it have most of the things that you need for the exam, lucky this time for a good test score.

Best calc to use for FE if you are accustomed to TI brand calcs. I like it a lot, great value.

I read the reviews before purchasing this calculator. This thing is gorgeous. Built to last and the feel of the keys is very durable. Love the way the cover clips on and completely protects the calculator. The back side of the calculator has 4 inlaid rubber feet that will stay on forever. If you want to take the lid off and clip it onto the back, it also has the 4 rubber feet. This calculator looks handsome and not faddish. Easy to see the characters on the keys and easy to read on the display. If you are concerned about your child (or whoever) being rough on stuff, this is an excellent choice. Has tons of great reviews. It is more expensive but not that much more expensive. If you are one who is always misplacing or losing stuff then get a less expensive one. If you are concerned about long lasting durability, then get this one. It seems to be very statistics oriented according to my math tutor today. He has a Casio FX 260 solar and says it got him through all of his engineering courses. I also have a Casio FX 260 and my adult GED classes were supplied with this GED calculator. It is the official one used on the GED exam. My math tutor told me that I dont need one this advanced to get through Trig and Calc. but I love this TI-36XPro calculator and plan to learn how to use it. Comes with a nice little instruction manual, not like those stupid fold out sheets. Others reviews have commented on its use. I am emphasizing its appearance, build quality , design,and instruction manual. One person commented on the silver keys on the right being difficult to read, but it is a no brainer arrangement. It takes 1 second to learn them by position and you remember it forever. I plan on really enjoying using this calculator. I would compare it to the Subaru Cross Trek of automobiles. Hope this review helps someone. not learned how to use it yet; however

Even though Im not a heavy user of calculators, I like em. Last count I had about 30 around the house. I especially like owning the best out there...just to play with. Weird, I know. Even though I own high end CAS models in TI and HP, these require opening the manual just to navigate around the keypad and menus. I dont want to fire up a tank when a jeep will do. My primary area of mathematical interest is in number theory. Scientific calcs generally fail miserable for this purpose. But, for the most part, graphing functionality is not that critical to me. I frequently work on problems involving prime numbers, so I like that the TI-36X Pro can factor numbers upto 1,000,000, find gcd and lcm, do modular arithmetic, has good functionality with arrays and lists, including generating them by specifying a range of arguments for a function. The screen also displays in textbook format. The Ti-36X Pro provides all this while being about half the volume and weight of a typical graphing calc, and a fraction of the cost. Another advantage is the solar panel and button cell that run it. The power consumption of the cpu in graphing calcs is beyond what solar power can reasonably provide, and some eat AAAs like Cheerios. Because the TI-36X Pro is chip based rather than separate cpu and operating system, it does not have a full programming language and cannot be customized with apps, backed up or interfaced with a computer - features that most graphing calcs now provide. But the TI36X Pro is my current favorite for number theory operations that would otherwise require a spreadsheet or a graphing calc. Its also a great scientific calc, with a full quiver of operations for calculus, statistics, vectors, matrices, solvers, base conversion, etc. CAS would be nice, but this is impractical to developed for a chip based calc. I suspect you wont find a calc with more functionality without going to an o/s and cpu bases unit. Ok, its wonderful. There is a minor display problem (documented on Wikipedia) which may concern some, but I regard it as trivial. Now for my one peeve about this calc and how I resolved it. The shiny chrome buttons are too hard to read unless angled just right. Maybe you have better eyes than mine. Maybe you would just memorize these few buttons. But I couldnt live with it. Not a problem, I love taking things apart. I found the TI-30XS to have the same outer shell, so I swapped the enter and 4 math operator buttons between them. Unfortunately, access to the buttons is was more difficult than expected. Instead of finding the usual mounting screws for a circuit board, this calc has the board mounted by moulded plastic fasteners. It was designed to be permanently assembled, making what should have been a simple modification quite challenging. I used a soldering iron, but wasnt convinced this was the best way. Im not suggesting or recommending you try this (and will not be responsible for your results)! It could easily be botched. I did each disassembly / reassembly step on the TI-30XS first to have that experience before doing the same on the Pro. Be prepared to sacrifice at least the TI-30SX. I managed to get both reassembled, but ended up with my sin button upside down on the Pro and have been reluctant to disassemble it again, because remelting the fasteners would deteriorate the plastic further. There is a high probability for not getting one or both of the circuit boards to remount. If this happens, you could try inserting a thin piece of closed cell foam between the board and case back to provide enough pressure to hold the board in place during key presses.

I needed a scientific calculator to do complex calculations for a Ham Radio license exam. The big positive for me in this case is that you cant program and store formulas in the calculator, or it wouldnt be allowed to be used on the test. This may be a huge drawback for other uses, but in this instance it was a plus. There was a learning curve to learn how to actually use and format entries, but it wasnt terrible. The book that comes with it is decent in that regard. Hard to beat for the price. Solar powered. The display is primitive, but easy enough to read.

I’m taking a business math class that requires me to do a huge volume of simple calculations for which my TI-92 graphing calculator (that has served me well for 20 years) is simply overkill. Of course it is capable of doing everything I need, but it’s huge and cumbersome to use for basic math. With a compact size and amazing price, TI-36X Pro is perfect for real-world (non-scientific) math. For anyone with experience using TI graphing calculators, this is the perfect choice thanks to the EOS™ (Equation Operating System), MathPrint™ display, and curated subset of functions and features found on the graphing models. First, MathPrint displays math on the screen just humans write it on paper. On TI-89 and TI-92 graphing calculators, this is called Pretty Print (this may be different on newer models). For example, with MathPrint enabled, the calculator will display 3². If disabled, it would display 3^2 (like a “business” or “scientific” calculator would). This is a simple example—MathPrint can display roots, stacked fractions, and more complex symbols and formatting. EOS is to TI calculators as iOS is to iPhones and iPads. It’s the basic software that makes TI calculators behave consistently and predictably. Notably, this means (when MathPrint is enabled), TI-36X Pro evaluates expressions left-to-right using the EOS order of operations (parentheses, functions such as log(), fractions, exponents and roots, negation, permutations and combinations, multiplication then division, addition then subtraction, and conversions). As with other EOS calculators, it understands implied multiplication (i.e., 2(3) will be interpreted as 2×3) and uses a dedicated negation symbol, entered with the () key. This makes it easy to tell the difference between a minus operator and a negation symbol on the screen as in “2 – 3”. While it doesn’t display graphs, the TI-36X Pro supports variable storage (x, y, z, t, a, b, c, d), hex/bin/oct entry and conversion, easy fraction – decimal (and mixed number) conversion, LCM/GCD, data tables, random dec/int generation, function table, operation storage and one-touch recall, unit conversions, equation solving (i.e. 8 = 2x, solve for x), polynomial solver, system solver (2x2 linear equations, 3x3 linear system), and plenty more.

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!

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!!!
