解:188+97+12,
=188+12+97,
=200+97,
=297;
235+36+45,
=235+45+36,
=280+36,
=316;
372+89+38,
=372+38+89,
=410+89,
=499;
464+28+24,
=492+24,
=516;
597+24+3,
=597+3+24,
=600+24,
=624;
682-55-27,
=682-(55+27),
=682-82,
=600;
725×23×4,
=725×4×23,
=2900×23,
=66700;
8125×16,
=8125×8×2,
=65000×2,
=130000;
932×25×25,
=23300×25,
=582500.解析分析:结合运算符号和数字特点,利用运算定律简算;不能简算的按照运算顺序计算即可.点评:计算要做到灵活,注意运算符号与数字的关系.
