数学命题由条件(前提)和结论两部分组成.一般来讲,条件改变了,结论也随之发生相应的变化.将命题从特殊引向一般;从具体引向抽象;从低维拓向高维等,都可看作是将命题推广.本文仅就初等数学问题推广的几种主要方式谈一下自己的看法.1由特殊向一般作推广有些数学命题的结论是在特定条件下得到的,如果改变或取消某些约束条件,则所得命题可能会更具有普遍性.例1(2013年全国高中数学联赛B卷
Mathematical propositions consist of conditions (premise) and conclusions. In general, conditions change, and conclusions change accordingly. From propositions to special leads; from concrete leads to abstractions; from low to high Dimensions, etc., can all be seen as promoting propositions. This article only discusses some of the main ways in which elementary mathematics problems are promoted. 1 The conclusion that certain mathematical propositions are generalized from general to general is obtained under certain conditions. If you change or cancel certain constraints, the resulting proposition may be more universal. Example 1 (2013 National High School Mathematics League B
