【Abstract】 Based on the definition of weak magic square,the system of correlative algebra is studied by analogy. And then combined with the definition of abstract algebra,the algebraic system of the weak magic squares about two op--erations ■ and ■ is put forward: weak sum of magic square about ■ operation constitute algebraic system,semig--roups,commutative semigroups,groups,commutative groups; weak product of magic square about ·operation constitute algebraic system,semigroups,commutative semigroups constituting unite; The weak sum and weak pruduct of-magic square constitute algebraic systems and rings with respect to ■ and ■.更多还原
