StackVille Bank & Trust - Robbed!
The Robbery
The bank is being robbed. There are millions in cash in the vault. The lone robber takes the manager to the safe and demands he opens it.
The manager was scared, as he did not know the three numbers to the vault. He did know, however, where the bank president kept clues to the combination. He opened a drawer, pulled out a piece of paper, and read the clues:
