Martin,

Algebraic: You punch in "1", "+", "1" ,"=" then 2.0 pops up on the screen.
RPN: You punch in "1" ,"ENTER", "1", "+" then 2.0 pops up on the screen.

Electronic abacus.

This is true, but try it on a more realistic real world problem.

How about the the angle of view of an 85mm lens on a 30D:

AoV = 2 atan(sqrt(22.5² + 15²) ÷ (2 × 85))

Algebraic:
[2] [×] [atan] [(] [Sqrt] [(] [2] [2] [.] [5] [x²] [+] [1] [5] [x²] [)] [÷] [(] [2] [×] [8] [5] [)] [)] [=]: 25 keystrokes, and don't forget to close all parentheses.

RPN:
[2] [2] [.] [5] [x²] [1] [5] [x²] [8] [5] [enter] [2] [×] [÷] [atan] [2] [×]: 17 keystrokes, and absolutely no parentheses to forget.

Now, try comparing them with a complex problem.

So, nu! You have no brown sugar or cinnamon in your cupboard?

I was at work, so no.

Nick, i have to disagree, i hava a friend, when we were younger used to get $50 /week allowance i got $5

when he grew up he worked for his Dad, today he is a billionaire, and never put in a hard days work, it does happen

He's still livin off his dad though.

i haven't used a calculator in, well, since you were born

When I was born, there were no calculators, except, perhaps, the abacus.

Hehe...it's a bastardisation of a film quote...Jerry Maguire I think.

It is, but I was pisstaking

1 win, 1 loss I think so far...hoping to get promotion at the end of the season to the Premiership, we've been close the last 2 years and Sven is in charge now and I think he knows what he's doing

Liverpool are ok, the Champ League was odd without them in it. As long as it isn't Man U or Chelsea winning I don't mind

Sven!! It'll be good if they get up!

I hate manure with a passion. So as long as they don't win, or Chelski, I'll be a happy chappy.

Need to get back in, and show the other British teams how to win the Champions League, again.

its fun to just run up and press it like 50 times in a row while everyone standing there watches you do morse code on the elevator call button

you, sir, are 1st down the shaft

I was trying to explain to Martin in simple terms how you would input differently between the two. He has no need for it.

RPN makes a lot of sense once you think about it. A lot can go wrong with the algebraic way.

Exactly.

Some people said what do you expect him to say. I say to that you dodge it

Exactly what I commented. There is no need to take an extreme stance one way or the other. The reporter through the bait out there and Eli couldn't keep from chomping on it.

no, his Dad dies a couple of years ago, that's how he became a billionaire from a multi millionaire

I remember someone doing this while we both waited for the elevator to arrive. This was in the lobby of a 50 floor building which I had been in numerous times......That day wasn't a good day to annoy me......

Anyways, as we got in the elevator, I asked what floor he wanted, to which he said #38. I simply said okay and smiled......I then proceeded to button mash all the buttons I could until I hit #38 (think I hit about a dozen before his ). I proceeded to then get off on the first floor it stopped at and wistled on the way out. It just so happened that the second elevator had just arrived and let someone off on that floor, so I got on it and road smoothly directly to the 20th floor.

......Never did see him again.
