观察例题计算方法,计算下题例:计算:-55/6-(+92/3)-(-173/4)+(-31/2)原式=-55/6+(-92/3)+(+173/4)+(-31/2)=[(-5)+(-9)+17+(-3)

观察例题计算方法,计算下题例:计算:-5 5/6-(+9 2/3)-(-17 3/4)+(-3 1/2)原式=-5 5/6+(-9 2/3)+(+17 3/4)+(-3 1/2)=[(-5)+(-9)+17+(-3)]+[(-5/6)+(-2/3)+3/4+(-1/2)]=0+(-1 1/4)=-1 1/4.请仿照上面例题的计算方
观察例题计算方法,计算下题
例:计算:-5 5/6-(+9 2/3)-(-17 3/4)+(-3 1/2)
原式=-5 5/6+(-9 2/3)+(+17 3/4)+(-3 1/2)
=[(-5)+(-9)+17+(-3)]+[(-5/6)+(-2/3)+3/4+(-1/2)]
=0+(-1 1/4)=-1 1/4.
请仿照上面例题的计算方法,计算下面这题:
计算:(-2009 5/6)-(+2008 2/3)-(-4018 3/4)+(-1 1/2).
注释:如-2009 5/6意思是 负两千零九又六分之五.

观察例题计算方法,计算下题例:计算:-5 5/6-(+9 2/3)-(-17 3/4)+(-3 1/2)原式=-5 5/6+(-9 2/3)+(+17 3/4)+(-3 1/2)=[(-5)+(-9)+17+(-3)]+[(-5/6)+(-2/3)+3/4+(-1/2)]=0+(-1 1/4)=-1 1/4.请仿照上面例题的计算方
(-2009 5/6)-(+2008 2/3)-(-4018 3/4)+(-1 1/2)
=-2009 5/6+(-2008 2/3)+(+4018 3/4)+(-1 1/2)
=[(-2009)+(-2008)+4018+(-1)]+[(-5/6)+(-2/3)+3/4+(-1/2)]
=0+(-1 1/4)=-1 1/4.
