(480+240)÷(36-24)
2010÷15-11×12
2000-2000÷25+188
(512-475)×200÷37.
解:(1)(480+240)÷(36-24),
=720÷12,
=60;
(2)2010÷15-11×12,
=134-132,
=2;
(3)2000-2000÷25+188,
=2000-80+188,
=2108;
(4)(512-475)×200÷37,
=37×200÷37,
=7400÷37,
=200.
分析:(1)两个括号内的同时计算,最后算除法;
(2)先算除法和乘法,再算减法;
(3)先算除法,再算减法和加法;
(4)先算括号内的,再算括号外的乘法和除法.
点评:此题重点考查了学生对整数四则混合运算顺序和运算法则的掌握.
