A fun math problem:
In the game of Set, each card has between 1 and 3 of some shapes (squiggles, ovals, or diamonds) in either red, green, or purple, filled in either with nothing, or with a solid color, or with stripes. Supposing you love numbers more than anything else, let's translate every card into numbers as follows: each card has four attributes: number, shape, color, and fill.
- A card with one shape gets 1 for the number, a card with two shapes gets 2 for the number, and a card with three shapes gets 3 for the number.
- A card with squiggles gets 1 for the shape, a card with ovals gets 2 for the shape, and a card with diamonds gets 3 for the shape.
- A card with red gets 1 for the color, a card with green gets 2 for the color, and a card with purple gets 3 for the color.
- A card with no fill gets 1 for the fill, a card with solid fill gets 2 for the fill, and a card with stripes gets 3 for the fill.
