(-32)(+3)÷(-24)(-2)
= (-96)÷(+48)
= -96÷48 ﹤這部可以不寫
= -2
＊答案一定對，希望幫到你la~

先括號，再先乘除後加減！

(-32)(+3)÷(-24)(-2)
=-96 ÷(-24)(-2)
=-96/-24(-2)
=+4(-2)
=-8
因為(-32)(+3)要乘左去先,即係話(-32)X(+3),同負正得負,所以變成-96,之後-96要÷(-24)(-2),唔好以為要乘左(-24)(-2)先,如果佢有大括號先可以計先,所以-96÷-24,負負得正,等於+4,再之後,+4(-2),即係話又要乘,(+4)X(-2),正負得負,最後,就等於-8。

=(-32x3)÷(-24x-2)
=-96÷48

是括號乘括號先才÷
=(-32x3)÷(-24x-2)

一條數有兩個答案,,...真係好陰人囉...
2008-10-04 2:23 am
(-32)(+3)÷(-24)(-2)
= (-32)x(3)÷(-24)x(-2)
= (-96)÷(-24)x(-2)
= 4x(-2)
= (-8)

上面2位計錯啦= ="
2008-10-03 18:39:08 補充：
下面一位又計錯埋= ="
佢本身冇用方括 [ ]
點解會後面果2個乘埋左先除架= ="
= (-32)x(3)÷(-24)x(-2)
= (-96)÷(-24)x(-2)
= 4x(-2)
= (-8)

-32x3=-96
-24x-2=48
-96/48=-2
所以答案係-2

下面果位傻的嗎??
點解要計後面先都唔識??
你幼稚園??
括號代表x
2008-10-06 22:36:44 補充：
先x後除未聽過?
-24x-2=48
-96/48=-2
所以答案係-2
