Storyboard Text

  • We need to solve (8x9) + 3^2 x (5-1) I will help you by using PEMDAS
  • P parenthesis E exponent M multiplication D dividsion A addition S subtraction
  • Parenthesis are first.  (8x9) = 72 and (5-1) = 4 Exponents are next.  3^2 = 9 Now are equation becomes 72 + 9 x 4
  • Multiplication and division carry equal weight so just solve from left to right.   The same holds true for addition and subtraction.
  • Now are equation is easy to solve! 9 x 4 = 36, and 72 + 36 + = 108
  • Just follow PEMDAS and you will always get the correct answer!!
