分析:(1)運(yùn)用乘法分配律簡(jiǎn)算;
(2)運(yùn)用加法交換律簡(jiǎn)算,交換位置時(shí)注意運(yùn)算符號(hào);
(3)運(yùn)用加法結(jié)合律簡(jiǎn)算;
(4)先算小括號(hào)里面的除法,再算小括號(hào)里面的減法,最后算括號(hào)外的除法;
(5)根據(jù)連續(xù)減去兩個(gè)數(shù)等于減去這兩個(gè)數(shù)的和簡(jiǎn)算;
(6)運(yùn)用乘法分配律簡(jiǎn)算.

點(diǎn)評(píng):本題考查了基本的簡(jiǎn)便運(yùn)算的方法,特別是對(duì)運(yùn)算定律的使用;要記住這些簡(jiǎn)算的形式,能靈活運(yùn)用.
