The positions of rational numbers a, B and C on the number axis are known as shown in the figure, which is simplified as follows: | ABC | / ABC + (a + B + C) / | a + B + C | - | BC | / BC - (C-B) / | C-B | - a / | a On the number axis, if a and - 2 B are equal to 1, C is equal to - 1 The above error, a on the number axis wants to be equal to - 4, B is equal to 1, C is equal to - 1, which is only determined by my naked eye, because there is no upload map,

The positions of rational numbers a, B and C on the number axis are known as shown in the figure, which is simplified as follows: | ABC | / ABC + (a + B + C) / | a + B + C | - | BC | / BC - (C-B) / | C-B | - a / | a On the number axis, if a and - 2 B are equal to 1, C is equal to - 1 The above error, a on the number axis wants to be equal to - 4, B is equal to 1, C is equal to - 1, which is only determined by my naked eye, because there is no upload map,

On the number axis, I want to be able to and - 4 B is equivalent to 1, and - 4 B is equivalent to 1, and C is equivalent to - 1, because a * b * C = positive number, so |abc / ABC = 1, because a + B + B + C = negative number, so (a + B + B + C) / |a + B + B + B + B + B + B + C = -1, because B * C = negative number, so / BC / BC = - 1; because (c-b-b) = negative number, so (C-B) / (C-B) / (c-b-b-b-b) / / / / / / ABC / ?124/ / / / - | BC | / BC - (C-B) / | C-B | - A / | a | = 1 + (- 1) + (- 1) + (- 1) + (- 1) + (- 1) = - 3
