数学中有些问题,不是进行许多计算,分析数量关系或图形的变换来得出答案和结论的.问题的条件也不是算式、数字和图形.而是一些相互关联的事实.题目需要根据条件进行有根有据的分析推理,作出正确的判断,得出问题的答案,这类问题就是逻辑推理问题.在解决逻辑问题时要求遵循形式逻辑的基本规律:同一律:两个思想如果有着同一外延,则二者彼此相同,所发表的每一个思想,如果它的外延尚未发生变
There are some problems in mathematics, not many calculations, analysis of quantitative relationships or graphical transformations to arrive at the answers and conclusions.The problem conditions are not arithmetic, numbers and graphics, but some interrelated fact.The subject needs to be rooted according to the conditions Evidence-based analysis, to make the right judgments, to come to the answers to questions, such problems is the logical reasoning.In logic problems to solve the basic rules of formal logic to follow: the same law: If the two thoughts have the same extension, The two are identical to each other, and every thought published, if its extension has not changed yet
