You were so close! The correct answer is -33. You did all of your steps right in the beginning, but -30 - 3 is not 28, it's -33. If you have to add or subtract and you have 2 negative signs, then you keep that sign and add the numbers together. I remember this by singing a song to myself to the tune of Row Row Row Your Boat to help me. My 7th grade math teacher came up with it for our class.
