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 provide
a 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 years
before 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.
