A high school has a strange principal. On the first day, he has his students perform an odd opening day ceremony:

There are one thousand lockers and one thousand students in the school. The principal asks the first student to go to every locker and open it. Then he has the second student go to every second locker and close it. The third goes to every third locker and, if it is closed, he opens it, and if it is open, he closes it. The fourth student does this to every fourth locker, and so on. After the process is completed with the thousandth student, how many lockers are open?

Well by that logic, wouldn't it have to be so that every locker that is a perfect square totaling less that 1,000 would remain open? Given that, all perfect squares up to 31 are less than or equal to 1,000. 32 is too large. This means that 31 lockers are open.
