数学运算中有连续化简的原则 ,凡事都有正反两个方面 ,有些数学问题在求解的过程中不宜化简 .以下列举一些此类问题并分析不当化简的后果 ,以提醒大家在解题时注意 .1 简易逻辑运算问题例 1 命题 p:能被 5整除的数的个位数是 0 .命题 q:能被 5整除的数的个位数是 5.求命题 p
In mathematics operations, there are principles of continuous simplification, and everything has positive and negative aspects. Some mathematics problems should not be simplified in the process of solving. Listed below are some of these issues and analysis of the consequences of improper simplification to remind everyone Notes on the problem. 1 Simple Logic Operation Problem Example 1 Proposition p: The number of digits divisible by 5 is 0. Proposition q: The number of digits divisible by 5 is 5. The proposition
