Order of operations is the set of rules that tells you the correct sequence to solve a math problem. The order of operations consists of 3 sets of symbols and they are Parentheses, Exponents, and Multiplication/Division followed by Addition/Subtraction. The acronym PEMDAS stands for Parentheses, Exponents, Multiplication/Division, Addition/Subtraction and is used to help remember the order of operations.
