    I boutgh an HP pocket calculator in Chicago in 1990. Unfortunately
there was no more these good old reverse polish notation models and I
got one wich decoded formulas in the mathematical style with
parentheses. I think the RPN was more convenient for a pocket
calculator. But note things are very different when you need to remember
everyting you type than when you can read and edit the whole formula in
the text editor.
