How to set up accordingly?

  • @egreg, ohhh I never imagined that the order could be a solution. Simpler than this, impossible.

The correct order is the reverse, first newtxtext and then newtxmath.



notations: $Y=N-\operatorname{int}(U)$


enter image description here

In newtxmath.sty we find


and \rmdefaultB is \rmdefault, which still is Computer Modern if newtxtext has not yet been loaded,

  • Do you mean "if newtxtext has not yet been loaded"?
