add a question about whether an example demonstrating a sometimes confusion thinking of precedence of a prefix minus sign would be beneficial to add |

Line 11:
-2^2 (or -2**2, depending on what plain ASCII notation one wants to follow), along with some sort of authoratative reference, would be useful to add to the page.
I wonder this because the algebraic result of -4 is not necessarility obvious to people who read the notation (I know that I've seen arguments in web forums/newsgroups/mailing lists over whether this should be -(2*2) or (-2*-2). It seems like specifically noting the correct algebraic interpretation would be worthwhile in the context of operation precendence and notation. <span style="font-size: smaller;" class="autosigned">—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/134.243.209.109|134.243.209.109]] ([[User talk:134.243.209.109|talk]]) 14:10, 26 May 2009 (UTC)</span><!-- Template:UnsignedIP --> <!--Autosigned by SineBot-->
