=-12
係人都計到啦

(+a)(+b)=+ab
(-a)(+b)=-ab
(+a)(-b)=-ab
(-a)(-b)=+ab
x乘0=0,
所以
4乘(-1又3分之1)乘0-4乘3=0-12=-12
(-a)(+b)=-ab
(+a)(-b)=-ab
(-a)(-b)=+ab
x乘0=0,
所以
4乘(-1又3分之1)乘0-4乘3=0-12=-12

由於０乘乜野都係０的關係
所以呢段"乘(-1又3分之1)乘0"完全唔駛計
0 - 4 *3 = -12
所以呢段"乘(-1又3分之1)乘0"完全唔駛計
0 - 4 *3 = -12

4*(-1&1/3)*0-4*3
=4*(-4/3)*0-4*3
=-16/3*0-4*3
=0-12(由於０*任何數＝０)
=-12
=4*(-4/3)*0-4*3
=-16/3*0-4*3
=0-12(由於０*任何數＝０)
=-12

4乘(-1又3分之1)乘0-4乘3
=...
first , step by step
4乘(-1又3分之1)
= -16/3
-16/3乘0-4
=-16/3乘-4
=64/3
64/3乘3
=64
4乘(-1又3分之1)乘0-4乘3=64
=...
first , step by step
4乘(-1又3分之1)
= -16/3
-16/3乘0-4
=-16/3乘-4
=64/3
64/3乘3
=64
4乘(-1又3分之1)乘0-4乘3=64
