  • 解题思路:(1)(3)按照从左到右的顺序计算;

    (2)先算小括号里面的减法,再算括号外的除法;

    (4)先算小括号里面的除法,再算括号外的乘法;

    (5)先算乘法,再算减法.

    (1)824÷4×3,

    =206×3,

    =618;

    (2)(601-246)÷5,

    =355÷5,

    =71;

    (3)201+232-365,

    =433-365,

    =68;

    (4)82×(434÷7),

    =82×62,

    =5084;

    (5)703-26×25,

    =703-650,

    =53.
