Directions/Instructions: There are rules to be followed in performing a series of more than two operations on whole numbers by applying the PMDAS or GMDAS rule correctly. Example: (15 + 5) x 2 = 5-4=N Solution: Here are the rules/steps: (15 + 5) x2 + 5 - 4 = N ) 2 + - Perform the operation inside the grouping symbol first or parenthesis. -Multiply or Divide from left to right. 20 X 2 = 5 - 4 = N 40 : 5 - 4 = N -Multiply or Divide from left to right. 8 -4 = N -Add or subtract from left to right. 4 = N - Therefore in (15 + 5) x 2 + 5-4, the answer is 4​
