整体思想就是在思考问题时,把注意力和着眼点放在问题的整体结构上,把一些彼此独立而又紧密联系的数或量当作一个整体来处理。遇到某些复杂问题时,若能善于综合运用已学的知识,用整体思想去分析问题,常可收到意想不到的效果。下面以解答一次方程组问题为例,浅说整体思想的应用。 The overall idea is to focus attention on the overall structure of the problem when thinking about the problem, and treat some numbers or quantities that are independent but closely related as a whole. When you encounter certain complicated problems, you can often receive unexpected results if you are good at using the learned knowledge comprehensively and analyzing the problem with your overall thinking. The following is an example of solving the problem of the one-equation system, and the application of the whole idea is briefly discussed.
