How do you save a keynote onto a USB?

[NeustomiemDit]

I'm trying to put in the equation: f={64/R if R<(or equal to)2300 {2R if R>2300 I know how to write the basic if, then, else part, but my knowledge ends at only getting it to display an given statement. I need it to return an answer to the correct equation based on the original input. I can give more info if this isn't clear enough. Thanks

Why do you need a Polish Notation? Why such a disoriented subject with the thread content that are you really asking?

Search about it here: http://en.wikipedia.org/wiki/Polish_notation
