分析:(1)按照有理數(shù)的加法和減法分別進(jìn)行計(jì)算即可;
(2)用(-12)分別與括號(hào)中的每一項(xiàng)進(jìn)行相乘,然后再進(jìn)行相加即可;
(3)先把小數(shù)化成分?jǐn)?shù),再提取公因式,即可求出答案;
(4)按照有理數(shù)的混合運(yùn)算的法則,先算乘方和絕對(duì)值,再算乘除,后算加減即可;
(5)先去掉絕對(duì)值,再進(jìn)行統(tǒng)分,即可求出結(jié)果;
(6)先算乘方,再算乘除,然后再進(jìn)行相加即可.

點(diǎn)評(píng):此題考查了有理數(shù)的混合運(yùn)算,解題的關(guān)鍵是根據(jù)有理數(shù)混合運(yùn)算的法則分別進(jìn)行計(jì)算,先算乘除,后算加減,有括號(hào)的要先算括號(hào)里面的,注意結(jié)果的符號(hào).
