The position of rational numbers a, b and c on the number axis is shown in the figure: If m=|a+b|-|b-1|-|a-c|-|1-c|, then 1000m=______.
As shown in the figure, b < a <0,1> c >0,
A+b|=-(a+b),|b-1|=1-b,|a-c|=c-a,|1-c|=1-c,
1000M=1000×(-a-b-1+b-c+a-1+c)
=1000×(-2)
=-2000.
Therefore, the answer is:-2000.
