I'm not an expert when it comes to math, but based on a conversation on IRC about the following calculation:
//var %c = 48 / 2 (9 + 3) | //say $calc(%c)
mIRC returns it as 24 despite the protest of one person that it [the correct answer] is in fact 288 (or two.)
Google also confirms that the calculation is 288.
[00:36:03] <+Jigsy> .g 48 / 2 (9 + 3)
[00:36:04] <%^> (48 / 2) * (9 + 3) = 288
