Question

-的相反數(shù)是________，絕對(duì)值是________，倒數(shù)是________．

Answer 1

        -
分析：本題利用相反數(shù)、絕對(duì)值和倒數(shù)的性質(zhì)解題．
解答：-的相反數(shù)是1，絕對(duì)值是1，倒數(shù)是-．
點(diǎn)評(píng)：此題考查了相反數(shù)、絕對(duì)值和倒數(shù)的性質(zhì)，要求掌握相反數(shù)、絕對(duì)值和倒數(shù)的性質(zhì)及其定義，并能熟練運(yùn)用到實(shí)際當(dāng)中．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)值是它的相反數(shù)；0的絕對(duì)值是0．
倒數(shù)的定義：若兩個(gè)數(shù)的乘積是1，我們就稱(chēng)這兩個(gè)數(shù)互為倒數(shù)．
相反數(shù)的定義：只有符號(hào)不同的兩個(gè)數(shù)互為相反數(shù)，0的相反數(shù)是0．
