Double?

No

• Each half of a domino carries its own number of spots, and the tile's value is the two halves added together: 1 + 4 = 5.
• Turning the tile round swaps the halves without changing its value, which is the commutative property of addition: 1 + 4 = 4 + 1 = 5.
• The same tile shows the subtraction facts too: 5 − 1 = 4 and 5 − 4 = 1.
• A full double-six set has 28 tiles: every pair of numbers from blank to six once each, counting a tile and its turned-round twin as the same tile.
