right; GnS means: good fb ps who are scots
OpenStudy (anonymous):
does GUS mean the same thing/
OpenStudy (amistre64):
no, it used different notation, which suggests it means something else
OpenStudy (amistre64):
GuS are all good fb ps and all scots

that is a descent way to remember it
OpenStudy (amistre64):
u is to unite; take everything from one pot and mix it in with all the stuff from another pot; combine it all together in a big stew
OpenStudy (amistre64):
n is to be nitpicky; take out what each pot has the same. take the corn from potA and the corn from potB and place them together into potC
OpenStudy (anonymous):
