In school a couple of years ago I learned about post and pre something. I cannot remember what it is called. anyways it looks like this x+y*z then you would write it like this (post) xyz*+ then for pre I think it would go +*xyz anyways, I need to know what this is called, and if you have an extra minute could you refresh me on how it works. Thanks I really appreciate it. Sincerely, Ronald
