I Reverse Polish Notation Heart T-Shirt - $9.95
Be still my geeky heart! Neatoramanaut Ana models this wonderfully geeky I Reverse Polish Notation Heart T-Shirt.
What's a Reverse Polish notation? It's a mathematical notation where the operator (e.g. +, -, x) follows the operands. Those of you who have the old HP-10C series calculator are probably nodding in nostalgia right now!

Or is it something to do with taking shiny notation, and rubbing it with a filthy rag to render it dull and patinated?
When I was at school, the math teachers always started the year telling "you can get any calculator you want, but no HP."
There I lifted hand and grinned I already had one.
kinda spoiled a good thing.
"FORTH LOVE IF HONK THEN"
But why did you have her model it in a kitchen?
Please do beter next time.
If you ever have to write something to evaluate mathematical expressions input by users as text, you'll wish everyone wrote 'em in RPN. I always convert the expression (like "(1+2)/12+88") into a nice RPN stack, then calculate the answer.
I wish HP still made an RPN calculator in that notecard format. I thought that was brilliant design. I know the HP12 is still out there but, it isn't RPN. I guess the business types can't handle RPN.
I still think in RPN with a slight slide rule accent.

I wish they still offered the 15C; I do more engineering than financial. I have a 15C emulator that I use on the computer as a calculator, and my mobile phone calculator lets me set it to RPN mode!
>Sadly, this t-shirt isn't really correct. Reverse polish notation
>is stack based so this should be "I notation polish reverse <3"
Not true - RPN is one "variable" so it's correct as it is. It could be: "I, Reverse Polish Notation, <3".
I wish our tutor had looked like that.
