scientific method.

George: Here are pictures of my three children.
Mary: How nice; how old are they?
George: You're a scientist, you figure it out.
Mary: OK, give me a hint.
George: If you multiply their ages, the result is 36.
Mary: I need more information.
George: If you add their ages, the sum is the age of your
oldest child.
Mary: I almost have it, I need one more clue.
George: The blue eyed child is the oldest.
Mary: I figured it out using the scientific method.

After Mary made her hypotheses about the ages of the children,
she added the ages and looked at the sum. What part of the
