Board game requiring formation of mathematical equations - has counters carrying figures or function signals for adding to previous plays

摘要

The board is divided into 361 squares and has on it several equals signs (1); one central the others over the board area. Several squares are coloured to represent the functions of addition (4), subtraction (2), multiplication (5) and division (3), for points multiplication. Three corners are marked 0. Square counters are used, red backs being marked with function signs; white backs, numbers. Each player chooses a number of both types of counter. The first player forms an equation using the central equal sign. Other players make other equations, using their own counters and those equations on the board. The player with the most points is the winner.
