Let me give you an example to understand. For example, to solve /x-5/+/x/+/x+3/> 1, we first find the "zero point", that is, to make the formula in each absolute value equal to 0, and we get 5, 0, 3, because /x/ is equivalent to the absolute value of /x-0/. At this time, we will disassemble it in sections, which will lead to the positive and negative problems after removing each absolute value symbol. We decompose from left to right on the number axis, here is1.x.
