下午第三节课,初一(1)班教室出奇的安静,这是什么原因呢?原来数学兴趣小组的成员们正围着一幅名画上的“难题”在冥思苦想.名画《难题》是俄国著名画家波洛丹洛夫·别林斯基的代表作.这个难题是要求用口算很快地求出(102+112+122+132+142)÷365的结果.小婷心直口快,首先打破了沉默:“本题若先算平方,再求和,而后做除法,运算繁杂.能巧解吗?” In the third class of the afternoon, the first class (1) classroom was surprisingly quiet. What was the reason? The members of the original math interest group were wrestling with a “puzzle” on famous paintings. The famous painting “Puzzle” was Russia. The masterpiece of the famous painter Bolotenlov Belynsky. The challenge is to quickly calculate the results of (102+112+122+132+142) ÷365 using oral calculations. Xiaoting expresses his emotions and breaks the silence first. : “If this question is first squared, then sum, and then divide, do arithmetic. Can it be solved?”
