Now its time to test our brain.
1. By moving one of the following digits, make the equation correct. 62 - 63 = 1
2. You have a fox, a chicken and a sack of grain. You must cross a
river with only one of them at a time. If you leave the fox with the
chicken he will eat it; if you leave the chicken with the grain he will
eat it. How can you get all three across safely?
Let me see who is the smartest?
