Question

11、絕對(duì)值不小于1而小于3的整數(shù)的和為

0

．

Answer 1

分析：求絕對(duì)值不小于1且小于3的整數(shù)，即求絕對(duì)值等于1和2的整數(shù)．根據(jù)絕對(duì)值是一個(gè)正數(shù)的數(shù)有兩個(gè)，它們互為相反數(shù)，得出結(jié)果．

解答：解：絕對(duì)值不小于1且小于3的整數(shù)有±1，±2．故其和為0．
故答案為：0．

點(diǎn)評(píng)：本題主要考查了絕對(duì)值的性質(zhì)．絕對(duì)值規(guī)律總結(jié)：絕對(duì)值是一個(gè)正數(shù)的數(shù)有兩個(gè)，它們互為相反數(shù)；絕對(duì)值是0的數(shù)就是0；沒(méi)有絕對(duì)值是負(fù)數(shù)的數(shù)．
