分析:(1)先算小括號(hào)里面的乘法,再算括號(hào)外的除法;
(2)先算小括號(hào)里面的除法,再算小括號(hào)里面的加法,最后算括號(hào)外的乘法;
(3)先運(yùn)用加法交換律計(jì)算小括號(hào)里面的運(yùn)算,再算括號(hào)外的乘法;
(4)運(yùn)用湊整法簡(jiǎn)算.
解答:解:(1)4503÷(6×5),
=4503÷30,
=150.1;
(2)(356+3916÷89)×69,
=(356+44)×69,
=400×69,
=27600;
(3)(125-327+275)×26,
=(125+275-327)×26,
=(400-327)×26,
=73×26,
=1898;
(4)99999+9999+999+99+9,
=(100000-1)+(10000-1)+(1000-1)+(100-1)+(10-1),
=(100000+10000+1000+100+10)-(1+1+1+1+1),
=111110-5,
=111105.
點(diǎn)評(píng):本題考查了四則混合運(yùn)算,注意運(yùn)算順序和運(yùn)算法則,靈活運(yùn)用所學(xué)的運(yùn)算定律進(jìn)行簡(jiǎn)便計(jì)算.
