My daughter, who’s five, has been learning addition of late. She knows a lot of the single-digit addition, like one plus two, three plus three, like that, but what’s funny is that instead of saying, “One plus two equals three,” she tends to say, “Plus one plus two equals three.” It’s that extra “plus” that prefaces the statement that totally makes me think she’s doing math via Polish notation.
I know, only a computer geek would get that.

Hi Jon my wife and I will be relocating to the Klamath Falls area soon from the Spokane,Wa area. I have become quite fond of talking with bloggers in the Spokane area and found that there is much information to be learned from them. Not knowing the area very well I was wondering what you could tell us about Klamath Falls and surrounding area.
Don’t some HP calculators make you type it in that way, too?
Nevermind — looked it up, it’s apparently REVERSE polish notation that’s used on HP calcs:

(that entry is far more in-depth, that’s for sure)
