学习有理数的运算法则,不仅要准确地理解和掌握法则,灵活地应用法则进行计算,而且更重要的是要善于弄清法则的来龙去脉并从中学习数学思想方法,这样才能提高数学思维水平和数学学习能力.下面就有理数运算法则中体现的几种重要的数学思想方法归纳如下. Learning algorithms for rational numbers not only requires an accurate understanding and mastering of laws, but also applies the rules flexibly, and more importantly, they must be good at clarifying the ins and outs of rules and learning mathematics ideas and methods from them so as to improve mathematics thinking level and mathematics learning. Ability. Here are some of the important mathematical thinking methods that are embodied in the rational number algorithm.
