-|-2/3|-|-1/2*2/3|-|1/3-1/4|-|-3|
-|-2/3|-|-1/2*2/3|-|1/3-1/4|-|-3|
-|-2/3|-|-1/2*2/3|-|1/3-1/4|-|-3|
答案：-4又1/12
-|-2/3|-|-1/2*2/3|-|1/3-1/4|-|-3|
=-2/3-1/3-1/12-3
=-4又1/12
绝对值取其大小 |a|=a（a>=0）
|a|=-a（a
-|-2/3|-|-1/2*2/3|-|1/3-1/4|-|-3|
=-2/3-1/3-1/12-3
=-1-1/12-3
=-4又1/12
-|-2/3|-|-1/2*2/3|-|1/3-1/4|-|-3|
=-2/3-1/3-1/12-3
=-4-1/12
=-4又12分之1
