三阶幻方都有哪些填法呢?你认真研究过吗?学完了有理数的加减法,我对课本第22页“实验与探究”中的幻方问题进行了统计调查,发现很多同学对幻方问题很感兴趣,却不知道该怎么填.因此我和我们班的数学迷们对三阶幻方问题进行了研究,得出了两种比较容易的填法.三阶幻方就是将9个给定的数填入3×3的方格中,使得处于同一横行、同一竖列、同 Third-order magic squares have what fill it? Have you studied it carefully? After learning the addition and subtraction of rational numbers, I conducted a statistical survey of the magic squares in the textbook “Experiment and Exploration” on page 22 and found that many Students are very interested in magic square problem, but do not know how to fill. So I and our class math fans on the third-order magic square problem has been studied, come to two easy filling method. Third-order magic square That is, fill in the 3 × 3 squares with 9 given numbers so that they are in the same row, the same column and the same column
