Great RPN Calculator – Complex RPN Calculator Review

I have beening using RPN logic calculators since the HP-35 in 1972. When the reviewer here complained about the missing "equal" key It brought back early memories of people asking me the same thing about my HP-35, the fact is no RPN calculator has one. When solving a problem you don't, as in an AOS system enter 2+2=4, instead you do 2 enter 2 + and that eguals 4. This doesn't seem to make much since until you start getting into a complex calculations and are able to solve it just as you might do it on a chalkboard working from the inside out, being able to see the results of each step before finally seeing the final answer. Several decades ago I schooled a high school math teacher in the use of an HP RPN calculator. This teacher had a blanket ban on calculators in his classes feeling they where a cheating tool. Once he understood RPN logic he realized its' resource as a teaching tool because it teachs how to solve a problems as illustrated in a text book, and by preventing you from entering something in the wrong way. To any student out there that is learning higher mathmatics for the first time I highly recommend this App using RPN logic will pay off in better understanding and better grades. The fact this App if free is just icing on the cake. I agree with the one reviewer being able to see the "stack" would be really nice.
