    ok, so lets take this one step at a time. First focus on the inside, you have 3-(-6). what does that equal?

    no, that's not right. You're multiplying 3 and -6, but you should be subtracting them, I think that's where you mistake may be natalie :)

    what is (3) - (-6)? what happens when you subtract a negative number?

    (3) - (-6) is the same as (3) + (6) you can think of the two negatives cancelling out to form a positive

    almost! just follow what @jim_thompson5910 said. Once you get the answer to taht, all you have to do is negate it (due to the negative on the outside) and you're good to go! :)

    -[3-(-6)] -[3+6] -[9] -9

    so you basically evaluate 3-(-6) to get +9 then you change it to -9 since there's a negative out front
