分析:(1)先算小括號(hào)里面的減法,再算括號(hào)外的除法,最后算乘法;
(2)(3)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;
(4)運(yùn)用乘法分配律簡(jiǎn)算;
(5)先算括號(hào)里面的加法,再算括號(hào)外的除法,最后算加法;
(6)先算小括號(hào)里面的加法,再算中括號(hào)里面的減法,最后算括號(hào)外的除法.

點(diǎn)評(píng):這類型的題目先觀察算式,看能不能運(yùn)用簡(jiǎn)便運(yùn)算的方法簡(jiǎn)算,若不能就要按照運(yùn)算順序逐步運(yùn)算.
