This past weekend was the Washington Post Hunt, a large-scale puzzle event held in Washington, DC, with puzzles by humorist Dave Barry and a few of his friends. One of the puzzles required you to scour the Sunday comics in search of hidden numbers, planted there by the artists.
Can you find the hidden numbers in each of these comic strips?
In the three puzzles below, replace each of the letters with a digit from 0 to 9 so that the equation is correct. A letter must be replaced with the same digit every time it appears. Each of the three puzzles uses a different code, and each puzzle has a unique answer.
