what do opposite sides of a dice add up to
Dice Opposite sides of a modern die traditionally add up to seven, implying that the 1, 2 and 3 faces share a vertex.[14] The faces of a die may be placed clockwise or counterclockwise about this vertex. If the 1, 2 and 3 faces run counterclockwise, the die is called "right-handed", and if those faces run clockwise, the die is called "left-handed". Western dice are normally right-handed, and Chinese dice are normally left-handed.[15]
