A mathematical game apparatus comprising:

• (a) a rectangular box having a base, four walls attached to the base and adjoining walls configured to have a storage space, and said walls displaying open top edges;
• (b) the rectangular box further having colored opposite sides selected from a plurality of colors;
• (c) each top edge having an open rectangular shaped groove;
• (d) a dowel rod mounted within each groove supported at each end of the rod;
• (e) each of two smaller dowel rods mounted on smaller sides of the rectangular box having one cube, each cube with a hole through two opposite faces, each cube freely suspended and rotatable on the dowel rod to display other four faces;
• (f) four visible faces on each cube on smaller rods displaying numerals 1, 2, 3, and 4 in a numerical order;
• (g) each of two longer dowel rods mounted on longer sides of the rectangular box having nineteen cubes, each cube with a hole through two opposite faces, each cube freely suspended
• and rotatable on the dowel rod to display other four faces;
• (h) four visible faces on each of nineteen cubes on longer rods displaying a combination selected from a numeral, a mathematical symbol, and blank colored faces;
• markings on the cubes on the first side of the rotating cubes 1, 2, 3, 4, 5, 6, 7, 8, 9, +, 1, 2, 3, 4, 5, 6, 7, 8, 9;
• with markings on the second side of the rotating cubes 18, 17, 16, 15, 14, 13, 12, 11, 10, −, remaining cubes blank;
• markings on the third side of the rotating cubes on one side of the game board 8, 12, 18, 36, 45, 54, 56, 72, 81, ÷, remaining cubes blank;
• markings on the third side of the rotating cubes and on the opposite side of the game board 6, 9, 16, 24, 25, 28, 42, 63, 64, ÷, remaining cubes blank;
• markings on the fourth side of the rotating cubes blank except for the middle cubes on both sides with the symbol X;
• (i) two 12 sided dice and three 20 sided dice storable in the storage space of the box;
• markings on the first of the 12-sided dice 1, 2, 3, 4, 5, 6, 7, 8, 9, 3, 5, 7;
• markings on the second of the 12-sided dice 1, 2, 3, 4, 5, 6, 7, 8, 9, 4, 6, 8;
• markings on the first of the 20-sided dice 4, 5, 7, 10, 12, 15, 16, 18, 20, 21, 24, 28, 35, 36, 42, 49, 54, 56, 64, 72;
• markings on the second of the 20-sided dice 1, 2, 3, 6, 8, 9, 12, 14, 18, 24, 25, 27, 30, 32, 36, 40, 45, 48, 63, 81;
• markings on the third of the 20-sided dice 4, 6, 8, 9, 12, 16, 21, 25, 27, 28, 32, 35, 36, 42, 48, 49, 54, 56, 64, 72.
