用奇偶数性质解题的方法,叫奇偶性分析。本文将先列举奇偶数的性质,然后用实例来说明它们在解题中的妙用。1.奇数≠偶数.2.奇数+奇数＝偶数;偶数+偶数=偶数.3.奇数十偶数＝奇数.
The method of solving the problem with odd and even properties is called parity analysis. This article will first enumerate the nature of odd and even numbers, and then use examples to illustrate their magical use in problem solving. 1. Odd Numbers Even Numbers 2. Odd Numbers + Odd Numbers = Even Numbers; Even Numbers + Even Numbers = Even Numbers 3. Odd Odds Even Numbers = Odd Numbers.
