  • 解题思路:(1)先算乘法,再算加法;

    (2)(6)按照从左到右的顺序计算即可;

    (3)先算乘法,再算减法;

    (4)先算减法,再算乘法;

    (5)先算加法,再算乘法.

    (1)548+24×22

    =548+528

    =1076;

    (2)54×23÷9

    =1242÷9

    =138;

    (3)972-21×23

    =972-483

    =489;

    (4)36×(278-219)

    =36×59

    =2124;

    (5)(134+235)×27

    =369×27

    =9963;

    (6)96÷4×97

    =24×97

    =2328.
