构造高阶f次幻方的加法

摘要

给出构造高阶f（=1，2，…为自然数）次幻方的加法，并证明两个f次幻方的和仍是一个f次幻方；两个f次完美幻方的和仍是一个f次完美幻方．%The addition method that can be used to build high orders f-multi magic square was given. Two theorems were proved: Add up two f-multi magic squares and you would get another f-multi magic square; This new f-multi magic square would be f-multi perfect magic square if they are f-multi perfect magic squares.
