Exponents, Parentheses, and the Order of Operations

 … used to show repeated multiplication  2 x 2 x 2 = 2 3 “2 to the third power”  Special case: Any number to the zero power is one: N 0 = 1  When the base is negative, consider if the negative is INCLUDED in parentheses or not…

 P – Do any operations in parentheses first.  E – Evaluate any exponents next.  MD – Multiply or Divide in order from left to right.  AS – Add or Subtract in order from left to right.
