Thesix operations are addition, subtraction, multiplication, division,exponentiation, and grouping, and their order of precedence isoften remembered using the acronym PEMDAS.Each of the letters in PEMDAS represents an operation and itsorder of priority:PEMDASarentheses (grouping)xponentsultiplyivideddubtractAre you taking both the ACT and theSAT?
