    81÷3+27÷9+2

    ------------------------------

    講 解

    ------------------------------

    先乘除後加減,所以要先算81÷3跟27÷9

    81÷3=27、27÷9=3

    27+3+2=32

    ------------------------------

    答:32

    ------------------------------

    除習慣以"/"表示

    81/3+27/9+2=27+3+2

    =32 #

    "*"習慣代表乘法

    新注音用全形打出「/」

    再選字就可以選到囉^_________^
