Why is the number 10 afraid of seven?
Why is the number 10 afraid of seven?
Because seven ate nine, and 10 is next.

pretty neat, nice interface. good content. was a looking for a RPN calculator.
RPN or DAL?
RPN or DAL?
CASE A: Solve the following expression: (8 6)(7 – 5)
With a normal calculator, assuming you have memory functions, you have to enter:
[8][ ][6][=] [M ] [7][-][5] [x] [MR] [=]while, with an RPN calculator you just enter:
[8][ENTER][6][ ] [7][ENTER][5][-] [x]—
i guess the thing here is that theres a stack with the 8 and 6 piling up and the 7 and 5 go with whats in the stack.
RPN required only 9 keystrokes instead of the 11 required by a standard calculator.
