It should always give a reliable answer, the problem is that the mnemonic is often taken too literally (which is obvious in the FB thread). It's not a great tool IMO because it's flawed in that the implication is that division comes before multiplication and addition before subtraction which is not the case, the components of any equation are solved left to right in their particular tier of operations. -- Rob Studdert (Digital Image Studio) Tel: +61-418-166-870 UTC +10 Hours Gmail, eBay, Skype, Twitter, Facebook, Picasa: distudio -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
