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

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.

I bought the TI‑36X Pro Calculator while preparing for engineering exams and it has quickly become my go-to calculator for both studying and everyday calculations. The multi-line display is one of the best features. Being able to see equations exactly as they’re typed makes it much easier to catch mistakes when working through longer problems. It also handles fractions, matrices, complex numbers, and unit conversions surprisingly well for a non-graphing calculator. Pros Clear multi-line display Powerful functions for engineering and science Allowed on many standardized exams Durable and easy to navigate once you learn the layout (even my 11yo uses it) Cons Not a graphing calculator Some advanced functions take a little time to learn Overall, this is a fantastic option for students in engineering, math, or science who want something more capable than a basic scientific calculator without stepping up to a full graphing model. This is also a really nice calculator for middle school students! Highly recommended.

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 that's not permitted on the FE exam so I chose this one. Upon using it I must say that for a non-graphic calculator it's 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 I'm 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 it's supposed to. However if you don't like this there is a feature to turn it off. This is especially useful for when you're calculating something like a parallel resistance circuit and you want to see that big fraction to make sure you didn't make a mistake. Of course no review is complete without listing the gripes. There's 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 don't 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 you've 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 you're not used to these "multipress" buttons. That's basically it. For a non-graphing calculator I give it a 9/10. Comparing budget calculators, I've 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. I've never had a Casio calculator so I can't compare. With this many features and usability at the price of $17 or so it's 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!

Even though I'm 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 don't 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. It's 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 won't find a calc with more functionality without going to an o/s and cpu bases unit. Ok, it's 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 couldn't 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 wasn't convinced this was the best way. I'm 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.

This is a requirement for most college classes but and its versatile. It works for multiple classes and easy to navigate. It comes with a sort of protective case. The only downside I would note is that it seemingly has no off button so I have to wait for it to turn off by itself.

I first bought this calculator shortly after it came out in 2012. I was halfway through engineering undergrad at the time and it quickly became my go-to calculator. The calculus functionality blew my mind at the time as most scientific calculators did not have that at the time. I used it all throughout grad school and now I use it for work in R&D industry. I have multiples of these calculators including my desk at work, the lab at work, and at home. In fact I once bought like 5 of these just to make sure I (and my colleagues) always have one within reach in the lab. What can I say, it does everything I need it to do without any cruft. Graphing calculators just aren't practical or useful for a working engineer (or me at least) when I have easy access to python and excel. And otherwise, this just does everything I need from a desk calculator. Since I'm a huge nerd I occasionally check to see if there are any new scientific calculators out there that are better. And I've yet to find one that can replace the TI-36X Pro for me. I recommend this calculator to anyone from high school or college students to full-time engineers and scientists that need a scientific calculator.

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?

It’s a nice calculator. Took a while to get here but it does the job. The buttons are a little different then your TI high level series, but it has all needed functions.

Tengo alrededor de 10 meses con la calculadora, por lo que me he animado a contarles la experiencia que he tenido con ella. Al principio es un poco tardada la transición entre usuarios de Casio a esta calculadora ya que tanto las funciones como la notacion que se usa es diferente, pero vale totalmente la pena, sobre todo por el display que puede mostrar operaciones y resultados anteriores al mismo tiempo, nunca había tenido una calculadora con esa capacidad y vaya de lo que me estaba perdiendo, es increíble el tiempo que te ahorras e incluso el desgaste mental de siempre tratar de aprenderte algunos resultados con varias cifras. Otra ventaja es la forma en que se insertan las operaciones, es mucho mas claro y se presta menos a confusión(por uso de paréntesis) ya que puedes escribir todo como lo escribirías en una libreta. Ahora lo que me parece un poco incomodo es que el signo menos no puedes usarlo como se te de la gana, hay dos tipos de menos, la operacion aritmetica y el signo como tal que indica cuando un numero es negativo, si por alguna razon usas el simbolo de sustraccion en una operacion como por ejemplo: (12)^-12 te dara un error, tienes que usar el signo de menos, el cual es (-) (asi es la tecla en la calculadora) y de esa forma no tendras problema alguno, la verdad es que te acostumbras demasiado rapido y no veo que sea una razon para no comprar esta GENIAL y POTENTE calculadora. Yo la uso para mi Ingeniería en Electrónica y me va de 10 para todas mis materias las cuales no son básicas, ya que ya estoy por concluir la carrera. Espero les sea de ayuda mi experiencia con esta calculadora que definitivamente es BUENA, BONITA Y BARATA!

Elle fait très bien le boulot

This is the best scientific calculator that I've ever used. It provides a lot of the functionality of the Ti-84 graphing calculator for a small fraction of the price. There are few other calculators on the market that provide comparable functionality - namely the Casio FX-991ES/FX-115ES and the Sharp ELW516XBSL. However this calculator is the best of the group. What sets this calculator apart from the pack is its ease of use and excellent usability. You don't need to read the manual to figure out how to use it, and its features are very usable. Examples: Big, High Resolution Display: All the three high end scientific calculators (this, the casio, and the sharp) have pixel grid displays and can show expressions in their written mathematical form. However this calculator's 4 line display can show more on the screen than any of the other calculators. This makes long calculations easier, makes matrix entry much more usable, data tables more usable, and data entry for statistics much easier. Unique (in this class) capabilities of this display include: - See up to 4 expressions and results at a time. The calculator puts the result on the same line as the expression when it fits comfortably. The Casio and Sharp only let you see one calculation at a time, and you must scroll back to see previous calculations. - 3x4 augmented matrix entry (for a 3 variable linear system) where the entire matrix can be seen at once. On the Casio, you have to enter larger matrices one line at a time, and on the Sharp you can only enter one coefficient at a time. - 4 row * 3 column data entry for statistics: you can see 4 rows of 3 column data at a time, plus a data entry line below. On the Casio, you can only enter X and Y values rather than having 3 arbitrary lists, and the display can only show 3 rows of 2 column data at a time. The Sharp is also limited to 2 variable XY pairs, and as a further limitation you can only enter/view one XY record at a time. Thanks to the better display and better display use, the Ti-36X Pro is by far the most capable of the pack. No Complicated Mode Switching: In the Casio/Sharp sense of modes, the TI-36X Pro has only one mode. It can do everything in that mode. There is no separate mode for integration, statistics, data entry, solving systems of different types, etc. When working under time constraints, switching between modes and navigating elaborate nested menus wastes time and breaks one's chain of thought. Losing all calculation history on a Casio/Sharp when switching modes doesn't help either. On the TI-36X Pro, just press one button to do what you want without switching mode. Want to enter data for stats? Just press the DATA button and start entering data into the table. Want to jump to solving a cubic equation? Just press poly-solve and solve your polynomial. Want to jump back into your stats? Press DATA and you'll be back with all your old data intact. Once you're done with your stats, press CLEAR and you'll be back at the regular calculator window with your calculation history and saved variables just as you left them. Numerical Integration, Numerical Differentiation, Series Summation, and Sequence Product: All these features are quick, accurate, and need no explanation to use. Note that the numerical integration algorithm used here is faster and more accurate than the Simpson's Rule used on the Sharp. The sequence product is a handy feature that you don't see on other calculators. Overall, this is a fantastic calculator. I do recommend reading the manual though. This calculator has a ton of handy features that you probably aren't aware of. With that said, I have a few minor criticisms: - The 2x2 system solver shows the AX + BY = C form rather than a 2x2 matrix. This may be more beginner friendly, but its annoying to have to press enter twice to move between variables. You need to press enter twice because it lets you change the sign between AX and BY from + to - and back. This is a useless feature that slows down operation. A regular 2x3 (2x2) augmented matrix (as used by the 3x3 solver) would be more efficient. - You need to press the up button twice and then press enter to edit the previous expression. On the Casio, you only need to press up once and then start editing right away Notwithstanding these minor criticisms, I recommend this calculator whole heartedly. It's a must have for Engineers and Scientists.

La TI 36 X PRO è una calcolatrice di alta gamma. Consente di svolgere tutte le operazioni necessarie di pre Algebra, Algebra e Trigonometria, Statistica e quelle più avanzate di Analisi Matematica. Inoltre ho trovato molto utile la funzione Math Print che consente di visualizzare le principali operazioni e formule così come si presenterebbero scritte. Molto utile anche la possibilità di poter vedere espresso in frazione un risultato in numero decimale, ove possibile. Inoltre la calcolatrice è robusta e resistente. Texas Instruments è sempre una garanzia di qualità. Una cosa che ho apprezzato in un vecchio modello TI degli anni 90 è che a distanza di 30 anni è ancora funzionante e le scritte sui tasti non sono affatto sbiadite ma sembrano appena stampate. Sinonimo di grande qualità.

Good
