How can a +4 become a -1? Posters should be more careful if they are serious about their education.
Originally Posted by pickslides To finish the problem you must create a common denominator I only looked at these 2 lines...hence noticed the switch from + to -
I think the poster should re-supply the question.

Posters should be more careful if they are serious about their education. I would say + because 45-90 < 0 and so for the answer to be > 0 it would need to be +400
