Question

【題目】絕對(duì)值小于4的整數(shù)有 ．

Answer 1

【答案】0，±1，±2，±3
【解析】解：根據(jù)絕對(duì)值的定義，則絕對(duì)值小于4的整數(shù)是0，±1，±2，±3． 所以答案是0，±1，±2，±3．
【考點(diǎn)精析】認(rèn)真審題，首先需要了解絕對(duì)值(正數(shù)的絕對(duì)值是其本身，0的絕對(duì)值是0，負(fù)數(shù)的絕對(duì)值是它的相反數(shù)；注意：絕對(duì)值的意義是數(shù)軸上表示某數(shù)的點(diǎn)離開(kāi)原點(diǎn)的距離)．
