Is this just a definition because what we really care about is how much the vectors are "pushing" through the surface? Or is it an actual equality?

          This is just notation: $dmathbf S = mathbf n,dS$. Both sides are computing the flux of $mathbf F$, i.e., the net amount of $mathbf F$ pushing outwards across the surface.

            This is just notation: $dmathbf S = mathbf n,dS$. Both sides are computing the flux of $mathbf F$, i.e., the net amount of $mathbf F$ pushing outwards across the surface.
