在下列各題的橫線中,填上“偶”或“奇”字.
(1)奇數(shù)+奇數(shù)=
數(shù)  (2)偶數(shù)+偶數(shù)=
數(shù)
(3)偶數(shù)+奇數(shù)=
數(shù)  (4)奇數(shù)×奇數(shù)=
數(shù)
(5)奇數(shù)×偶數(shù)=
數(shù)  (6)偶數(shù)×偶數(shù)=
數(shù).
分析:根據(jù)數(shù)的奇偶性運(yùn)算性質(zhì):奇數(shù)±偶數(shù)=奇數(shù),奇數(shù)±奇數(shù)=偶數(shù),偶數(shù)×偶數(shù)=偶數(shù),奇數(shù)×奇數(shù)=奇數(shù),奇數(shù)×偶數(shù)=偶數(shù),進(jìn)行解答.
解答:解:(1)奇數(shù)+奇數(shù)=偶數(shù)  
(2)偶數(shù)+偶數(shù)=偶數(shù)
(3)偶數(shù)+奇數(shù)=奇數(shù)  
(4)奇數(shù)×奇數(shù)=奇數(shù)
(5)奇數(shù)×偶數(shù)=偶數(shù)  
(6)偶數(shù)×偶數(shù)=偶數(shù).
故答案為:偶,偶,奇,奇,偶,偶.
點(diǎn)評(píng):掌握數(shù)的奇偶性運(yùn)算性質(zhì),是解題的關(guān)鍵.
