I'm trying to enter a long chain of inequalities in math display mode. If I enter the expressions as I want them to, LyX will continue displaying them off the screen - so that they don't show up when I compile the pdf (and I cannot see what I am typing). Is there a way I can enter a long chain of expressions in display mode so that LyX displays them nicely? My only option so far has been to exit display mode when I'm too far right of the screen, hit enter and go back into display mode to enter the next line. However, this doesn't look too great on the pdf, and I have no idea when is a good time to shift to the next line anyway. I'm assuming there is a proper way to do this.
As people mentioned in the comments you should use
