**drwls**, Saturday, January 10, 2009 at 2:43pmIt could also be

(-2/25) -30 = - 32 2/5

or

17 - (19/25) -30 = -13 19/25

or a lot of other answers.

What you calculated was

(17-19)÷ [(5)(5) -30]= -0.4

If you don't understand the importance of when and how to use parentheses, you are going to have a lot of difficulty with algebra

The only parentheses are the ones in the denominator around the 5's
