a = ba2 = aba2 - b2 = ab-b2(a-b)(a+b) = b(a-b)a+b = b b+b = b 2b = b 2 = 1
Does this argument make sense?
a = ba2 = aba2 - b2 = ab-b2(a-b)(a+b) = b(a-b)a+b = b b+b = b 2b = b 2 = 1

Four people, A, B, C, and D, are on one side of a bridge, and they all want to cross the bridge. However, it's late at night, so you can't cross without a flashlight. They only have one flashlight. Also, the bridge is only strong enough to support the weight of two people at once. The four people all walk at different speeds: A takes 1 minute to cross the bridge, B takes 2 minutes, C takes 5 minutes, and D takes 10 minutes. When two people cross together, sharing the flashlight, they walk at the slower person's rate. How quickly can the four cross the bridge?
A black man, dressed in black, is crossing a road. He's blind and deaf. A truck is speeding towards him, with its lights turned off. The street lamps are also off and there's no moonlight. When the truck is about to hit the man, the driver hits the brakes and manages to stop just a few centimetres from him. How did the driver see the man?
