Question

-的絕對(duì)值是（ ）
A．-2
B．-
C．2
D．

Answer 1

【答案】分析：由-小于0，根據(jù)絕對(duì)值的代數(shù)意義：負(fù)數(shù)的絕對(duì)值等于它的相反數(shù)即可得到結(jié)果．
解答：解：∵-＜0，
∴|-|=-（-）=．
故選D
點(diǎn)評(píng)：此題考查了絕對(duì)值的代數(shù)意義：正數(shù)的絕對(duì)值等于它本身；負(fù)數(shù)的絕對(duì)值等于它的相反數(shù)；0的絕對(duì)值還是0，掌握絕對(duì)值的代數(shù)意義是解本題的關(guān)鍵．
