分析:(1)先算除法,再算減法;
(2)運(yùn)用加法結(jié)合律簡(jiǎn)算;
(3)根據(jù)減法的性質(zhì)簡(jiǎn)算;
(4)先算括號(hào)后里面的減法,再算括號(hào)外的除法;
(5)先把24分解成3×8,再運(yùn)用乘法結(jié)合律簡(jiǎn)算;
(6)先把156分解成155+1,再運(yùn)用加法結(jié)合律簡(jiǎn)算.
解答:解:(1)160-60÷4,
=160-15,
=145;
(2)194+59+41+106,
=(194+106)+(59+41),
=300+100,
=400;
(3)383-(183+29),
=383-183-29,
=200-29,
=171;
(4)480÷(67-43),
=480÷24,
=20;
(5)24×125,
=3×8×125,
=3×(8×125),
=3×1000,
=3000;
(6)156+45-55,
=155+1+45-55,
=(155-55)+(45+1),
=100+46,
=146.
點(diǎn)評(píng):此題是考查四則混合運(yùn)算,要仔細(xì)觀察算式的特點(diǎn),靈活運(yùn)用一些定律進(jìn)行簡(jiǎn)便計(jì)算.
