Question

奇數(shù)與偶數(shù)的和一定是奇數(shù)，奇數(shù)與奇數(shù)的和一定是偶數(shù)．

正確

．

Answer 1

分析：根據(jù)奇數(shù)、偶數(shù)的性質(zhì)，奇數(shù)+奇數(shù)=偶數(shù)，奇數(shù)+偶數(shù)=奇數(shù)，偶數(shù)+偶數(shù)=偶數(shù)．據(jù)此判斷即可．

解答：解：奇數(shù)+奇數(shù)=偶數(shù)，奇數(shù)+偶數(shù)=奇數(shù)，偶數(shù)+偶數(shù)=偶數(shù)．
因此，奇數(shù)與偶數(shù)的和一定是奇數(shù)，奇數(shù)與奇數(shù)的和一定是偶數(shù)．此說法正確．
故答案為：正確．

點(diǎn)評(píng)：此題考查的目的是掌握奇數(shù)、偶數(shù)的性質(zhì)．
