分析:(1)運用加法交換律與結合律簡算;
(2)先算括號內的除法,再算括號內的減法,最后算括號外的乘法;
(3)運用減法的性質以及加法交換律簡算;
(4)(8)(10)運用乘法分配律簡算;
(5)把88看作8×11,運用乘法結合律簡算;
(6)運用除法的性質簡算;
(7)兩個括號同時計算,最后算乘法;
(9)先算乘法,再算減法和加法.
解答:解:(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.
點評:此題主要考查整數(shù)的四則混合運算的運算順序和應用運算定律進行簡便計算.
