The benefit I am talking about is more than mental math. It is the math sophistication, how familiar and confident the student is with math tools and the approaches to model and solve problems.
From my experience of being TA in undergraduate courses, many US STEM students consider themselves "bad at math" and give up thinking too easily when they at least should try for a while. I think it is a clear sign that their high school education does not adequately prepare them in this aspect.
