i need help please.
newton middle school has a hall with 500 lockers, all of which are closed. five hundred students start down the hall. the first student opens every locker. the second student closes all the lockers that are multiples of 2. the third student changes (closes an open locker or opens a closed one) all multiples of 3. the forth student changes all multiples of 4. and so on. after all students have finished how many lockers will be open.
please explain how to solve it too.

All of the answers that gave an answer or a clue (except JM) are wrong.
Do what Jm said, kind of. This layout is much easier:
Write what happens to locker 1
Write what happens to locker 2
Write what happens to locker 3
. . .
A pattern develops rapidly.
If you run into a problem, use ‘add detail’ to describe it here for more help, but you need to actually do the work.
I know I didn’t help much, sorry. Are you in the sixth grade?
