InFix & PostFix notation

[pinkman]

Really interesting, thanks for the sharing.

Like it is written, as a RPN users I don’t like infix calculators and I have trouble using them, but algebraic advanced calculators such as the Prime have a great advantage: in case of an error in a long numeric calculation you can see and correct it. In RPN I often double check the calculation.

Another con of RPN that is not mentioned in the document: it is hard to read.
