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

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.

Muy funcional

I was really impressed with how much this scientific calculator does for the price. I use it for statistics and it has more built-in functions (one-variable, two-variable, and normal probabilities which are harder to find) than other scientific calculators at almost the same price. Plus it does trig, matrices, complex numbers, and even some calculus which I never saw other than on an expensive graphing calculator. It pretty much does everything the expensive calculator does other than graphing, and its very easy for a beginner to use. (Do not confuse with the TI-36X that is not the Pro; that is an older model which does less and is less user-friendly.)

very useful features like a system of equations solver or MathPrint

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.

Ive used a lot of calculators (scientific, graphing, and handheld computers), but this one does everything I need it to without needing to mess around with features I never use. Allowed throughout school and FE/PE exams too. Anything more complicated and Im probably using Octave or Matlab anyways. IMO faster to use than the Casio 991 series with basically the same features.

Great product. I just broke it accidently. Sorry.

I am a fan of this calculator, it is an updated version of the one I used through high school and part of college. I got this for my son for high school, it took a little bit to teach his some of the functions, but it made a real difference once he got the hang of it. It is something that is worth every penny.

This calculator calculates numbers correctly.

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.
