One source on the web (http://www.proofwiki.org/wiki/Symbols:Z) says the symbols for the integers can be written in LaTex as backslash Z. On the forum, that currently shows up as the two characters. [itex] \Z [/itex]

That source also say the notation [itex] Z_+ [/itex] is deprecated in favor of [itex] Z_{\ge 0} [/itex]. I approve! I never can remember whether [itex] Z_+ [/itex] includes zero or not.
