解答:解:(1)125×103-125×3,
=125×(103-3),
=125×100,
=12500;
(2)2700-425-175,
=2700-(425+175),
=2700-600,
=2100;
(3)125×88,
=(125×8)×11,
=1000×11,
=11000;
(4)41+127+59+173,
=(41+59)+(127+173),
=100+300,.
=400;.
(5)1300÷25÷4,
=1300÷(25×4),
=1300÷100,
=13;
(6)156×l0l-156,
=156×(l0l-1),
=156×100,
=15600;
(7)125×32×25,
=125×8×4×25,
=(125×8)×(4×25),
=1000×100,
=100000;
(8)49×99+49,
=49×(99+1),
=49×100,
=4900.
點(diǎn)評:完成本題要注意分析式中數(shù)據(jù),運(yùn)用合適的簡便方法計(jì)算.
