In addition to the typo reported for this page earlier in the forum, there is also a problem with the third code-example:

‘(add 1 2 3 4 5)

Though it may not be obvious depending on the font your browser uses, the quote symbol there is not the basic single-quote character (') that the text implies. It is the multi-byte character one usually gets from Microsoft Word, etc. This has two effects: (1) It prevents cut-and-paste from the PDF into a REPL, and (2) it *looks* like a backtick-quote (`), which might lead someone to enter that expression as:

`(add 1 2 3 4 5)

which would yield a different result than what (quote ...) yields.
