Vintage 1970 Sum-Up Equation Card Game | 3M Company

Vintage 1970 Sum-Up Equation Card Game by 3M Company. “Sum-Up is unique contest of skill in which 2 to 8 players compete against each other - and time as everyone attempts to create high scoring mathematical equations. Each of the four rounds of play calls for a different type of equation - addition, subtraction, multiplication and division. During a round, each player plays every hand once, thus eliminating the luck of the deal. Players’ scores are derived from the end result of each of their equations - and the player with the highest score at the end of four rounds wins!” In excellent used condition!
