分析:(1)(4)(7)根據(jù)乘法分配律進行計算;
(2)根據(jù)連減的簡算方法計算;
(3)先變形為125×8×11,再計算;
(5)根據(jù)加法交換律及結(jié)合律計算;
(6)根據(jù)連除的簡算方法計算;
(8)從左往右依次計算即可求解.
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)135×99
=135×(100-1)
=135×100-135
=13500-135
=13365;
(5)41+127+59+173
=(41+59)+(173+127)
=100+300
=400;
(6)1300÷25÷4
=1300÷(25×4)
=1300÷100
=13;
(7)156×l0l-156
=156×(l0l-1)
=156×100
=15600;
(8)568-235+65
=333+65
=398.
點評:考查了運算定律與簡便運算,四則混合運算.注意運算順序和運算法則,靈活運用所學(xué)的運算律簡便計算.
