解:(1)97-12×6+43,
=97-72+43,
=25+43,
=68;
(2)99×38+38,
=(99+1)×38,
=100×38,
=3800;
(3)67+25+33+75,
=(67+33)+(25+75),
=100+100,
=200;
(4)103×12,
=(100+3)×12,
=100×12+3×12,
=1200+36,
=1236;
(5)528-53-47,
=528-(53+47),
=528-100,
=428;
(6)26×4-125÷5,
=104-25,
=79.
分析:(1)先算乘法,再算減法,最后算加法;
(2)運(yùn)用乘法分配律簡(jiǎn)算;
(3)運(yùn)用加法結(jié)合律簡(jiǎn)算簡(jiǎn)算;
(4)把103分解成100+3再運(yùn)用乘法分配律簡(jiǎn)算;
(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)同時(shí)運(yùn)算乘法和除法,再算減法.
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.
