Question:

how do you add a constant over and over again? I have an HP12c and I would like to take a starting value and keep adding 128 to it.

I can do this by taking the original value 1240 + 128. One would do it like this:

1240 ENTER

128 +

This gives me a total to which I want to add 128 to. What is the easiest way to do that? I can hit ENTER and 128 + once again, but is there a better way?

On certain 'regular' calculators, one has to just hit the plus button and you get your answer. Is there something similar using RPN?

Thanks,

joe
