✔ 最佳答案
       [   1   (        1 )]
  -8 - [ 12- - ( -7 + 16- )]
       [   2   (        4 )]

       [   1   ( -28   65 )]
= -8 - [ 12- - ( --- + -- )]
       [   2   (   4    4 )]

       [ 25   ( 65-28 )]
= -8 - [ -- - ( ----- )]
       [  2   (   4   )]

       [ 50   37 ]
= -8 - [ -- - -- ]
       [  4    4 ]

  -32   13
= --- - --
    4    4

  -32-13
= ------
    4

  -45
= ---
   4

     1
= -11-
     4

同學,不用擔心,努力加油學習!

留意:

1/2 = 0.5

1/4 = 0.25

1/8 = 0.125 <-- 今次沒有用這個,但可能將來有用。

1/2=0.25

-8- [12.25-(-7+16.25) ]
=-8-[12.25+7-16.25]
=-8-12.25-7+16.25
=5
