A mathematical calculation board game comprises 128 playing pieces and a game board having 144 squares. The playing pieces are arranged on the game board according to certain game rules. The game board is divided into "blue" and "red" sides and is marked with red, blue, purple, white and orange game squares. Fifty squares contain the operators +, -, x DIVIDED . Each operator square has a blue square on one side of it and a red square on the other side. The operator squares are arranged in four files vertically and ten rows transversely. Ten purple squares are arranged transversely to divide the game board into its blue and red portions. There are 51 red game pieces, 51 blue ones, 10 purple ones, 10 white ones, and 6 orange ones. One red and one blue piece are marked with a "-". The remaining pieces are marked with numbers or numerical expressions. The players place the purple and white pieces on the purple and white squares, respectively; the red and blue "-" sign pieces on the red and blue "-" sign squares, respectively; and the red and blue numerical pieces on the red and blue squares, respectively. Each pair of red and blue pieces connected by an operator square forms a longitudinally or transversely arranged mathematical calculating problem. The 25 calculating problems on each side of the boundary are calculated by the player sitting on that side of the game board and the answers calculated by each player are added together as his score.
