答案

(1)37+125+63+175,
=(37+63)+(125+175),
=100+300,
=400;

(2)(630-125÷25)×6,
=(630-5)×6,
=625×6,
=3750;

(3)688-(534-112),
=688-534+112,
=(688+112)-534,
=800-(500+34),
=800-500-34,
=300-34,
=266;

(4)156×101-156,
=156×(101-1),
=156×100,
=15600;

(5)125×88,
=125×8×11,
=1000×11,
=11000;

(6)4700÷25÷4,
=4700÷(25×4),
=4700÷100,
=47;

(7)(750+120)×(35+65),
=870×100,
=87000;

(8)97×99+97,
=97×(99+1),
=97×100,
=9700;

(9)630-29×17+56,
=630-493+56,
=193;

(10)47×28+71×47+47,
=47×(28+71+1),
=47×100,
=4700.
