Question

【題目】偶數(shù)＋ =偶數(shù)
奇數(shù)× =偶數(shù)

Answer 1

【答案】偶數(shù)；偶數(shù)
【解析】解：例如：2+4=6，3×2=6，所以：偶數(shù)+偶數(shù)=偶數(shù)，奇數(shù)×偶數(shù)=偶數(shù).
故答案為：偶數(shù)；偶數(shù)
奇數(shù)與偶數(shù)的運算性質(zhì)：奇數(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)，偶數(shù)+偶數(shù)=偶數(shù)，由此舉例判斷并填空即可.
