在数学领域里存在着这样一些难题,题目本身解起来十分繁琐,令人望而生畏,但若能换一种思路,从特殊(最简单)的情形入手,寻找规律,并由此得出一般情形下的结论,问题将迎刃而解。下面我们一起解答两个问题: 问题1:计算33333333×33333334=? 这道乘法题的两个乘数分别为8位数,若直接相乘十分麻烦,但我们发现,这两个乘数存在着一个规律,即除了个位数分别为3和4外,其他位数均为3,由此可从最简单的情形入手,即:
In the field of mathematics, there are such problems that the problem itself is very complicated and daunting to be solved. However, if we can change our thinking and start with the special (simplest) situation and look for the law, we can conclude that under normal circumstances The conclusion, the problem will be solved. Let us answer two questions together: Question 1: Calculate 33333333 × 33333334 =? The two multipliers for this multiplication problem are 8-digit. If multiplying directly is very troublesome, we find that these two multipliers have A rule, that is, in addition to a single digit were 3 and 4, the other digits are 3, which can start from the simplest case, namely:
