How to get the correct answers on MyMathLab 2013

Its a little time consuming but you will get the correct answers. ***UPDATE*** SOOOOOOO apparently this does not work. I don't have a mymathlab account anymore since i finished the class so i cant really be sure whether or not this still works. But a mistake some people make is NOT SAVING THE PROBLEM before you start. this is the most important step before getting the answers because the problem and answers do change if you dont save it. So remember to save it before you do anything and it should work. If not, im really sorry it doesnt work :(
