The Rotational Challenge #1

I gave you four problems...you'll need to solve them to find Map #2.  I've hidden a few clues around the school to help you solve the Rotational Challenge #1 and find Map #2.    I am 100% positive that you walk by this clue every day that you are at school.  I know that doesn't narrow it down very much...so I will tell you that I have hidden it under Byron High School Science & Mathematics Center.  Find this clue and you'll know what to do with those numbers.  Good luck...
