There are four three-digit numbers that share this property: the number itself, its double and its triple contain each digit from 1 to 9 exactly once. For example, 192 is one of them because 192, 384, 576 contain 1 to 9 each once. 273 is another one of them because 273, 546, 819 contain 1 to 9 each once. Can you find the other two numbers and calculate the product of these two numbers?Correct answers: 23

Cast the first stone
Jesus saw a crowd chasing down a woman to stone her and approached them. "What's going on here, anyway?" he asked.
"This woman was found committing adultery and the law says we should stone her!" one of the crowd responded.
"Wait," yelled Jesus, "Let he who is without sin cast the first stone."
Suddenly, a stone was thrown from out of the sky, and knocked the woman on the side of her head.
"Aw, c'mon, Dad...," Jesus cried, "I'm trying to make a point here!"
