解答:
解:(1)24×(151+49)÷30
=24×200÷30
=4800÷30
=160;
(2)17×243+17×56+17
=17×(243+56+1)
=17×300
=5100;
(3)3600-(96×29+96)
=3600-96×(29+1)
=3600-96×30
=3600-2880
=720;
(4)35×[962÷(322-285)]
=35×[962÷37]
=35×26
=910;
(5)385-[16×(196÷14)]
=385-[16×14]
=385-224
=161;
(6)3952÷(46×64-2892)
=3952÷(2944-2892)
=3952÷52
=76.
点评:整数混合运算的关键是抓住运算顺序,正确按运算顺序计算即可.
