Is RPN the kind of syntax where you first press "1" and then "sin" to get
the calculator to return a numerical value of sin 1?

If so, it was one of the banes of the later years of my elementary school
(years 7-9, or so). Our math books had alot of little helpful boxes telling
you to solve various kind of problems on a calculator, all pretty uselss to
me since it was given in that kind of syntax, while my calculator only
accepted "normal" syntax (ie press first "sin", then "1" in the above
example).
