Exponents: explain difference between -27 4/3, (-27) 4/3

Postby MOUSETAILS » Mon Mar 30, 2009 5:56 pm

can anyone explain the difference between ( i will just use these numbers as examples)

-27 4/3 and (-27) 4/3

I am getting confused when the difference is when the number is just negative and when there are parenthesis around it
