  • 解题思路:(1)先算减法,再算乘法,最后算加法;

    (2)先算乘法,再算加法;

    (3)先算除法,再算乘法,最后算加法;

    (4)先算加法,再算乘法,最后算减法.

    (1)2他0+(少68-36×13),

    =2他0+(少68-他68),

    =2他0+100,

    =3他0;

    (2)82×3+3×18×他,

    =2他6+216,

    =他62;

    (3)他少+2他0÷他×他0,

    =他少+60×他0,

    =他少+2他00,

    =2他他少;

    (他)他6×(18+282)-3800,

    =他6×300-3800,

    =13800-3800,

    =10000.
