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

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

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.

Muy funcional

I bought this for my chemistry class. I would suggest going to YouTube and looking for videos instead of reading the manual. It a lot easier.

I had these for my years in highschool and now in college. it is the most reliable calculator out there with many of the basic functions. I believe everyone should use these on SATs because of their practicality.

More functions than you’ll need, but I wouldn’t buy a calculator with less functions, especially for the price. My son needed this for High School math. With that said, you’ll need time to learn more advanced functions, it’s a very powerful device. Graphing, get out.

Great product. I just broke it accidently. Sorry.

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.

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.

The picture shows silver flat keys with blackened math functioned symbols, but the one I got has total chrome keys and the symbols are not blackened out. The math function keys are difficult to see unless the light hits them just right,. I bought this calculator because it is approved for taking to my Ham Radio license test. I tested the calculators functionality against my 20 year old HP graphing calculator and a the math seems accurate .. at least for engineering. I like the rest of the calculator; fits good in the hands and the display is easy to read, but why the engineers would have ever gone with chrome math function keys is beyond me. They must have wanted to make it look cool, but cool it is not. Im going to keep it as it does what I need it to do, but I will be filling in the symbols with flat black so I can see them. if you find this calculator with different color keys, get it, or maybe find an older model. If you expect perfection, then pass on the calculator. Shame on the Engineers.. and to TI for allowing it to go out like this. They should try using it before putting it out on the production line.
