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

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.

If youre STEM and you dont have this calculator you are making a grave mistake. You cant use graphing calculators on many of the higher-level tests, and this calculator is very powerful with lots of built in constants and great floating point accuracy. It will also automatically simplify fractions for you and give results in exact fractional terms (especially trig functions) that most calculators would output as an approximated value (i.e. cos(30) = sqrt(3)/2 whereas a TI-84 or TI-30 would give 0.866). You can hit the key above enter to get the approximated value from that. Remember, you cant just use the table function to get this because your calculator will output an imprecise result. - Not with the TI-36X pro. Table function for days. Make sure you memorize Avagadros number, you need that to calculate molar mass and molecules. - 2nd > constant > 4 > enter = 3.02214179e23 Dont get in the habit of storing values to memory with your TI-84, you wont be able to do that on the test - 8 constants you can store to calculate values to greater accuracy than if you spent the time to type in 10-digit values. I often get a more precise result than some of my professors who use lower grade calculators (verified by Wolfram Alpha/etc; obviously half the time I get a different result Im just wrong =] ) And Im just a sophomore scratching the surface of this things capabilities, a couple of my professors and a friend of mine with a B.S. in Applied Mathematics say it never stops being useful late into your career.

I am used to TI format, so this is just right for me. I am a chemical engineer student (sophomore at the time of this review), but I bought this in high school. This suited me for most of my needs in high school. Fine for geometry stuff and can actually solve cubic and quadratic functions for x. Doing calculus on this using integrals and differentiating was slightly time consuming, so if time is a factor for that look for graphing calculators. For stats, I got through perhaps half of the class/functions necessary with this calculator. This doesnt graph but can generate data tables. Now for college uses. I attend UT, and calculators are usually not allowed. The ones that are (at least for the classes I take like chemistry, maybe biology, intro engineering courses, physics I think) dont allow graphing calculators. Thats where this thing shines. It can store data in several variables for easy access, scroll to previous calculations, solve quadratics and cubics, convert fractions/decimals, aaaaaaand access preloaded scientific constants like planks constant or avagadros number. The interface is well designed, and do not underestimate the ability of that fraction button that allows you to type a numerator and denominator for fractions within fractions. I have had this for over three years, and have never had a problem with it, or needed to change the battery. I would recommend this to anyone who needs a scientific calculator. TI 84 or 83 a thing of the past in college. If you need a graphing calculator, id say learn to use TI 89 in college (Might be banned in high school).

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.

very useful features like a system of equations solver or MathPrint

This calculator has become one of my favorites, I like that you dont have to worry about keeping it charged like some of the more advanced TI calculators.

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.

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.

This calculator calculates numbers correctly.
