TI-30XA

I like these Texas Instrument calculators. I had one back in '85 but it eventually packed up so I bought another one which was solar powered. That was difficult to use at home during the evenings as the 'solar power' didn't always providea display under lower light levels, so I purchased this one which is battery powered and solved the problem. I have given 4 stars instead of 5 due to the fact that I can't remove the protective case that comes with it and which will have to come off to change the batteries in due course. I'll (hopefully) prise it apart with a lever of sorts but it'll last a few yearsbefore then and I don't want to risk damaging it right now. Regarding fractions, it finishes them off. For instance it will show 1-1/12th rather than 13/12ths for an answer which the Classwhizz FX-991EX does.* I think I prefer this calculator for that reason, although it is not as powerful.* Correction....the Classwiz will show 1/2+7/12 = 13/12ths or 1-1/12ths or 1.083333333 and back again by using the S-D and shift buttons. Apologies for wrong info.

I used this calculator to pass a technical radio exam. Obviously, I didn't need all the functions this calculator provides, but it had everything I needed for my exam. I had purchased a different calculator before this and found it was missing some basic functions, such as 1/X and X^Y etc. This calculator has these functions.My only criticism is the lack of functionality using the ENG button, it doesn't allow you to move backwards and forwards through the different x10^x options, it only allows one press of the ENG button. One good function is the 3 memory stores, it will allow you to store values in Sto1, Sto2 and Sto3 and also recall any of them when needed.I have no major concerns with this calculator.

I wanted a calculator that had a few more functions than a basic machine, particularly one that used the proper order of calculation (MDAS etc). I also wanted one with a reciprocal function for easy calculations involving electronics. This calculator is just the job- cheap effective and seemingly quite robust.It arrived within days and was well packaged against knocks and drops. It does the job and has a case which protects it when not in use/Dellighted

Nothing fancy, just everything you need for an engineers calculator.Quick and easy to use, designed with a good understanding of the most common features required for quick calculations.If I want to do anything more complex, I write a program on a computer.

This is a pretty good calculator. Reasonably nice feel to the buttons.
