This trick works by converting each number from 1 to 63 into binary form.
Hey guys, my teacher does this game where she has 6 sheets of paper (she puts them on the overhead projector) that have numbers 163. Some have certain numbers, some dont. All you have to do is pick a number one63 and tell her yes or no for each sheet of paper. I get extra credit if i figure this out and I really need the credit, but I am stunned!
