分析:(1)運(yùn)用加法結(jié)合律簡(jiǎn)算;
(2)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;
(3)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)外的乘法;
(4)運(yùn)用了乘法分配律簡(jiǎn)算;
(5)根據(jù)連續(xù)除以?xún)蓚(gè)數(shù)等于除以這兩個(gè)數(shù)的積簡(jiǎn)算;
(6)先算小括號(hào)里面的減法,再算中括號(hào)里面的乘法,最后算括號(hào)外的除法.
解答:解:(1)36+42+64+158,
=(36+64)+(42+158),
=100+200,
=300;
(2)1600-217-483,
=1600-(217+483),
=1600-700,
=900;
(3)42×(66-400÷25),
=42×(66-16),
=42×50,
=2100;
(4)163×8+137×8,
=(163+137)×8,
=300×8,
=2400;
(5)4200÷25÷4,
=4200÷(25×4),
=4200÷100,
=42;
(6)672÷[6×(75-67)],
=672÷[6×8],
=672÷48,
=14.
點(diǎn)評(píng):本題中的簡(jiǎn)算方法都是比較常用的簡(jiǎn)便運(yùn)算的方法,要在平時(shí)多使用,靈活掌握.
