on Fee42 (simple RNP calculator) you don't need stack 220 twice, just calculate the Truck consume first, Car consume after, subtract and multiply by the gallon price.
Thanks for pointing me to Free42. The one I am currently using, RPN Anywhere, is good, but I think Free42 might have better key bindings, which makes calculations a lot more friendly. I tried only entering 220 one time, but that does not seem to work. Meaning that as soon as I do a calculation with the 220 (like 220, enter, 30, enter, ) all of the operands are gone and I need to enter 220 again to do the next calculation. The reason I did 220 twice in my demo was because I only had to press enter a second time instead of typing 220 (and enter) two different times. They are both equivalent of course. Which one is more efficient? I guess that's an open question. Thanks again.
