Answer 1

分析：根據(jù)奇數(shù)和偶數(shù)的定義：整數(shù)中，能被2整除的數(shù)是偶數(shù)，反之，是奇數(shù)；及奇數(shù)和偶數(shù)的性質(zhì)：
（1）奇數(shù)和奇數(shù)的和是偶數(shù)；
（2）奇數(shù)和偶數(shù)的和是奇數(shù)；
（3）偶數(shù)與奇數(shù)的積是偶數(shù)；
（4）奇數(shù)與奇數(shù)的積是奇數(shù)；
（5）偶數(shù)與奇數(shù)的積是偶數(shù)，偶數(shù)再加上奇數(shù)和是奇數(shù)；
（6）奇數(shù)與奇數(shù)的積是奇數(shù)，偶數(shù)與奇數(shù)的積是偶數(shù)；
進(jìn)而解答即可．

解答：解：奇數(shù)+奇數(shù)=偶數(shù)    奇數(shù)+偶數(shù)=奇數(shù)
偶數(shù)×奇數(shù)=偶數(shù)    奇數(shù)×奇數(shù)=奇數(shù)
奇數(shù)+偶數(shù)×奇數(shù)=奇數(shù)    偶數(shù)+奇數(shù)×奇數(shù)=偶數(shù)
故答案為：偶數(shù)，奇數(shù)，偶數(shù)，奇數(shù)，奇數(shù)，偶數(shù)．

點(diǎn)評：此題考查的是奇數(shù)和偶數(shù)的性質(zhì)，根據(jù)其性質(zhì)進(jìn)行分析即可．
