all the lights will be burnt out.

@alkoed Ha, that is so true. Though only 1 and 100 stay on because its skip counting by 100 no by squares.

[alkoed]

None of them will be on because none of them were screwed in.

I tried this for real: I hurt my fingers on the light switches, my electric bill went up $30 before my wife left me, then my house caught fire due to electical overload and burned to the ground, the neighbors called 911 to report arson, and the local sheriff arrested me as a suspected psycho trying to contact aliens by flashing messages in morse code! To top it all, I used up over 300 light bulbs before the law threw me in the nervous hospital with padded walls and bars on the windows. Help!

No wonder why I couldn't figure this brain teaser out, it's math! Regardless, I agree, this should be taught in public schools.
