... I'm looking for your advice.

Before commenting anything, I'd need some "philosophy": This calculator doesn't show an "=" so it may be RPN - on the other hand there are "( )" and "[ ]" keys. So what's the basic operation principle? Thanks in advance.


Edit: Personally, I prefer mathematical symbols over English abbreviations, e.g. √ over SQRT or 1/x over INV or e^x over EXP. NRT is hardly decodable unless you see it standing next to x^y. Printing English abbreviations is ok if you want to sell it to the British Empire exclusively, but you wrote about targeting mass production Wink
