It is funny, once I saw how clumsy an algebraiccalculator was to use for more complex
problems,I found the RPN entry to make more sense.When you actually work the problems, you
find thatit matches the order that you'd enter the values ona HP calculator.Doing
complex problem used to be either a lotof memory buttons or (()) buttons just to match
theequations.It goes something like this:Take these two numbers and add them together.Then
take these three numbers and add them together.Now multiply the results together.As
compared to:(3 +4 +5) * ( 2+7 )Dwight
