It is known that ABCD is four different rational numbers, AB < 0, A-B > 0, a + B < 0, and B + C = 0, CD = - 1, where (continue) | a | > 1, try to determine the size relationship of ABCD, and show it on the number axis. (number axis or something, write out the numbers, and use - to type out the interval of each number) that.. you should pay a little attention to the format, it's better to segment, otherwise you will have a headache. Thank you (bow)

∵ab0
∴a0
∵b+c=0
∴b=-c
∵dc=-1
∴c=-1／d
Number axis;
----c----a----0----1／d----b----＞
