Adding Latex Code?

I am trying to add latex code to my MATLAB Script, what I need is shown in the picture.

Currently, I have the code below, and the first two are working, but the 3rd code is not.

What am I doing wrong?

% 
% $$Adv(P) = -\vec{V} \cdot \vec{\nabla}(S)$$
%

% $$Vg = \bigg(-\frac{1}{\rho f}\bigg)\hat(k) \times \vec{\nabla}P$$
%

% $$ Adv(P) = \bigg(-\frac{1}{\rho f}{{\partial y}{\partial x}-{\bigg(-\frac{1}{\rho f}{{\partialy}{\partial x}$$
%

% $$=0$$

in the third line oyu have:

\partialy

which should read

\partial y

Second to last curly brackets.

Furthermore, you do not have disjointed curly brackets in the same line, the whole thing should read:

% $$ Adv(P) = \bigg(-\frac{1}{\rho f}{\partial y}{\partial x}-\bigg(-\frac{1}{\rho f}{\partial y}{\partial x}$$

Furthermore do you mean to have frac with the partial terms adn \bigg) anywhere?

% $$ Adv(P) = \bigg(-\frac{1}{\rho f} \frac{\partial y}{\partial x}-\bigg(-\frac{1}{\rho f}{\partial y}{\partial x}$$
