if you are going to write out a math equation you have to 1: know the math rules to know that you NEED parentheses and 2: you have to know where to PUT the ().
this teaches you math rules......but not if the teacher cant get it right.
in real life the equation is not written out for you so even with a calculator you have to know that you multiply/divide before + or - .
