As shown in the figure, the three points A, B and C on the number axis represent the rational numbers a, b and c respectively, and |a-b|-|c-a b-c|=______.

As shown in the figure, the three points A, B and C on the number axis represent the rational numbers a, b and c respectively, and |a-b|-|c-a b-c|=______.

According to the number axis, c >0, a < b <0,
Therefore a-b <0,c-a>0, b-c <0.
The formula = b-a-c+a+c-b=0.
Therefore, the answer is:0.

From the number axis, c >0, a < b <0,
Therefore a-b <0,c-a>0, b-c <0.
The formula = b-a-c+a+c-b=0.
Therefore, the answer is:0.

Given that a.b.c is the trilateral of triangular abc, how to simplify the absolute value of a-b-c plus the absolute value of b-a+c minus the absolute value of c-a+b?

A.b.c are the three sides of the triangle abc,
——》 B+c > a,
Original formula
=(B+c-a)+(b+c-a)-(b+c-a)
=B+c-a.
