2.      Evaluate Powers/Exponents (E).

3.      Multiply and/or Divide in order from left to right (MD).

4.      Add and/or Subtract in order from left to right (AS).

 

Evaluate the expression inside the Parenthesis

3[2( 9 ) - 3×2]              (Add : 8 + 1 = 9 )

3[18-6]                        (Multiply:2( 9 ) =18; Multiply: 3×2 = 6)

3[12]                           (Subtrct: 18 - 6 = 12)
