My science class is pretty small. There are just students in the class. My teacher, Ms. Microbe, has an unusual system for pairing us up for labs. She has given each of us a number from through , and on lab days, she pulls our numbers out of a bag to determine who is paired with whom. When we did our last lab, I happened to notice that the sum of each person's number with his/her lab partner’s number was a perfect square!!
