分析:(1)根據(jù)有理數(shù)的加法原則進(jìn)行計(jì)算即可;
(2)根據(jù)有理數(shù)的加法原則進(jìn)行計(jì)算即可;
(3)首先去掉括號(hào),減去一個(gè)數(shù)即是加上它的相反數(shù),然后再進(jìn)行計(jì)算即可;
(4)首先去掉括號(hào),然后把帶分?jǐn)?shù)化為假分?jǐn)?shù),進(jìn)行通分,再進(jìn)行分?jǐn)?shù)的加減計(jì)算即可;
(5)首先去掉括號(hào),把帶分?jǐn)?shù)化為假分?jǐn)?shù),小數(shù)和小數(shù)相加后,再把分?jǐn)?shù)通分后相加減,最后進(jìn)行計(jì)算即可.
解答:解:(1)原式=-33;
(2)原式=-13+8=-5;
(3)原式=-4-11+9
=-15+9
=-6;
(4)原式=
+++=
=16;
(5)原式=
+--7
=4-7
=-3.
點(diǎn)評(píng):本題主要考查有理數(shù)的計(jì)算,分?jǐn)?shù)的化簡(jiǎn),小數(shù)、帶分?jǐn)?shù)如何化為假分?jǐn)?shù)等知識(shí)點(diǎn),關(guān)鍵在于認(rèn)真的進(jìn)行計(jì)算.
