分析:分別根據(jù)非負(fù)整數(shù),分?jǐn)?shù),負(fù)有理數(shù),整數(shù)的概念對數(shù)據(jù)進(jìn)行分類.其中比較繁雜的數(shù)需要化簡后再判斷,如:-(-4)=4,-(+3.14)=-3.14,6%=0.06,-|-1|=-1.
解答:(1)非負(fù)整數(shù)包括正整數(shù)和0,其中-(-4)=4,所以非負(fù)整數(shù)有:-(-4),0,32;
(3)分?jǐn)?shù)包括正分?jǐn)?shù)和負(fù)分?jǐn)?shù),其中-(+3.14)=-3.14,6%=0.06,所以分?jǐn)?shù)集合有:-(+3.14),-
,6%;
(3)帶有“-”的有理數(shù),其中-(+3.14)=-3.14,-|-1|=-1;,所以負(fù)有理數(shù)集有:-(+3.14),-
,-|-1|;
(4)整數(shù)包括正整數(shù),0,負(fù)整數(shù),其中-(-4)=4,-|-1|=-1,所以整數(shù)集有:-(-4),-|-1|,0,32.
故答案為:
(1)非負(fù)整數(shù)集:-(-4),0,32;
(3)分?jǐn)?shù)集合:-(+3.14),-
,6%;
(3)負(fù)有理數(shù)集:-(+3.14),-
,-|-1|;
(4)整數(shù)集:-(-4),-|-1|,0,32.
點評:對數(shù)據(jù)進(jìn)行分類時,其中比較繁雜的數(shù)需要化簡后再判斷.其中要注意:整數(shù)包括正整數(shù),0,負(fù)整數(shù).
