2、求平均每块麦田的产量。

3、解:选基准数为450,则累计=12+30-7-30+23-21+18-11+25+11=50,平均每块产量=450+50÷10=455(千克)。

4、答:平均每块麦田的产量为455千克。

5、求一位数的平方,在乘法口诀的九九表中已经被同学们熟知,如7×7=49(七七四十九)。

6、对于两位数的平方,大多数同学只是背熟了10~20的平方,而21~99的平方就不大熟悉了。

7、有没有什么窍门,能够迅速算出两位数的平方呢?这里向同学们介绍一种方法——凑整补零法。

8、所谓凑整补零法,就是用所求数与接近的整十数的,通过移多补少,将所求数转化成一个整十数乘以另一数,再加上零头的平方数。
