The positions of rational numbers a, B and C on the number axis are shown in the figure. If M = | a + B | - | B-1 | - | a-c | - | 1-C |, then the value of - 1001 is? b a c ─┴────┴──┴───┴─┴─> 0 1 )There will be a reward for wealth before 10 o'clock this evening! It will be invalid if it is too late!]
It's the value of - 1001m!
m=|a+b|-|b-1|-|a-c|-|1-c|
|a+b|=-a-b
|b-1|=1-b
|a-c|=c-a
|1-c|=1-c
m=-a-b-(1-b)-(c-a)-(1-c)
m=-a-b-1+b-c+a-1+c
m=-2
So - 1001m = - 1001 * (- 2) = 2002
