近几年以来,不少数字兴趣爱好者们在特殊的多位数的平方运算方面总结过其运算规律,如152=225,252=625,112=121,1112=12321等等.在多年的求学过程中,在任意两位数平方运算方面,笔者也摸索出了一种简单易学的算法新定则,在此,把它撰写成一文,以便于和大家进行相互交流和学习.1两位数平方运算算式的演化 In recent years, many digital interest enthusiasts have summed up their operating laws in terms of special multi-digit square operations, such as 152=225, 252=625, 112=121, 1112=12321, etc. In the course of many years of study, In terms of arbitrary two-digit squared operations, the author also explored a new easy-to-learn algorithm rule. Here, I wrote it into a paper so that I could communicate and learn with each other. 1 Double-digit square arithmetic The evolution
