RPN makes my head hurt...
It is easy. It all depends where you put the operator.
Prefix +, 2, 2
Infix 2, +, 2
Postfix 2, 2, +
People like Infix because it is the way they were taught arithmetic. Two PLUS Two EQUALS Four.
But Postfix works best on calculators and computers. You just need to master the idea of a “Stack” and pushing numbers onto the stack and popping them off the stack.
Clear now?
“RPN makes my head hurt...”
I cannot use a normal calculator, they are like polish to me.
I may still have an rpn Ti calc somewhere.
Yes I have an 11c 12c 15c 16c and 41cv (with nav pac that supposedly belonged to some Hazelwood guy, but that is a whole other long story)
Thank god there are some decent android rpn phone apps, not as good as the windows phone app was but it works.
