Question

16、所有絕對(duì)值小于3.14的整數(shù)的乘積是

0

．

Answer 1

分析：根據(jù)絕對(duì)值的性質(zhì)，先求出所有絕對(duì)值小于3.14的整數(shù)，再將這些數(shù)相乘即可．

解答：解：由絕對(duì)值的性質(zhì)得，絕對(duì)值小于3.14的整數(shù)有0，±1，±2，±3，
因而所有絕對(duì)值小于3.14的整數(shù)的乘積是0．

點(diǎn)評(píng)：此題考查了絕對(duì)值的性質(zhì)，要求掌握絕對(duì)值的性質(zhì)及其定義，并能熟練運(yùn)用到實(shí)際當(dāng)中．
解此題要注意，0乘以任何數(shù)都得0．
絕對(duì)值規(guī)律總結(jié)：一個(gè)正數(shù)的絕對(duì)值是它本身；一個(gè)負(fù)數(shù)的絕對(duì)值是是它的相反數(shù)；0的絕對(duì)值是0．
