答案

(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×(101-1),

=156×100,

=15600.
