解:(1)原式=24-14-16+8=2;
(2)原式=1-2+5-5=-1;
(3)原式=
=8-8=0;
(4)原式=-
=-
;
(5)原式=0.75+3.25-9+0.125-0.625-0.125=-5.625=-
.
分析:(1)根據(jù)去括號(hào)法則,先去掉括號(hào),然后進(jìn)行計(jì)算即可;
(2)首先去掉括號(hào),同時(shí)對(duì)絕對(duì)值號(hào)內(nèi)的式子進(jìn)行計(jì)算,然后去絕對(duì)值號(hào),最后進(jìn)行加減法計(jì)算即可;
(3)首先法帶分?jǐn)?shù)化成假分?jǐn)?shù),然后在進(jìn)行計(jì)算即可;
(4)根據(jù)絕對(duì)值的定義,去掉絕對(duì)值號(hào),然后去掉括號(hào),再通分后進(jìn)行計(jì)算即可;
(5)首先法分?jǐn)?shù)化為小數(shù),然后根據(jù)絕對(duì)值的性質(zhì)、去括號(hào)法則,去掉絕對(duì)值號(hào)、去掉括號(hào),再進(jìn)行計(jì)算即可.
點(diǎn)評(píng):本題主要考查有理數(shù)的加減法法則、絕對(duì)值的定義、去括號(hào)法則,關(guān)鍵在于認(rèn)真的進(jìn)行計(jì)算,正確的去括號(hào),取絕對(duì)值.
