  •                2(3+4)= 2(7)=14
  • 2)  E: Then do exponents:
  •                2(3+4)2= 2(7)2=2(49)= 98
  •                (2x5 ) / (x3 ) = 2x(5-3)
  • 3)  MD: Then Multiplication and Division: 
  •                 1 +6/2+4*3 =  1+ 3+12= 16
  •             When several multiplications and divisions occur together, go from left to right.
