Bunuel
Can I write the highlighted part like the bold part?
----y----x----0--------------
----x---------0----y---------
---------y----0---------x----
--------------0----x----y----


No. |y| < |x| means that x if further from 0 than y is. Is x further from 0 than y is in your examples?

I get my answer. Thank you so much...
