我酷爱数学,尤其是喜欢研究那些有趣的问题.一次听到同学议论:算平方这么麻烦,要是能有一种平方速算的方法该有多好啊.我听了以后,心想,是啊,算平方在数理化中经常用到,要是真能探索出一种简便的运算方法,岂不可让同学们从繁琐的运算中解脱出来? I love mathematics, especially like to study those interesting issues. I once heard classmates talk about it: If you think of squareness as a hassle, if there is a square way of counting, how good it will be. After I listened to it, I thought, oh yes. Squares are often used in mathematics and physics and chemistry. If we can really explore a simple operation method, shouldn’t our students be freed from tedious calculations?
