Axiom talk:Five-Segment Axiom

Note that as square brackets do not render perfectly when sized appropriately, I have replaced them with round ones. This is also consistent with house style, which can be found on Definition:Parenthesis:

"Some authors, when writing complicated statements with nested parentheses, use differently shaped brackets for each different parenthesis, in an attempt to make it clearer which brackets go with which substatements. However, some have the opinion that this does not actually aid comprehension and can add unnecessary confusion - especially when particular bracket styles are being used for particular mathematical tasks, as they frequently are.

It also happens, unfortunately, that square brackets do not render well in all browsers when they have been automatically scaled by our rendering software.

Therefore it is recommended that on ProofWiki round brackets are used throughout for parenthesis."

(Yes I know I just added most of the above.)

It's one of those points which needs to be explicitly mentioned in the House Rules page, and it's on my list of things to do on a rainy weekend. --prime mover 06:11, 29 January 2012 (EST)

Then you have to let me use $\circ$ for concatenation of functions, because I don't like too many parentheses. (By the way, at least in the states, I believe it's common to learn that notation in grade/high school) --GFauxPas 06:14, 29 January 2012 (EST)
