The above fraction is what I would like to achieve

What I have so far is

$ begin{bmatrix}

0 \

0 \

1 \

1 

end{bmatrix}   - frac{ begin{bmatrix}

0 & 0 & 1 & 1 

end{bmatrix}  begin{bmatrix}

1 \

1 \

1 \

1 

end{bmatrix}}{begin{bmatrix}

1 & 1 & 1 & 1 

end{bmatrix}  begin{bmatrix}

1 \

1 \

1 \

1 

end{bmatrix} }$

and it looks like this

You also get several errors from that input.

what are the errors? my code compiles so I didn't notice any errors

The second $ causes TeX to leave math mode before your equation is finished. You should put it all the way at the end (after end{bmatrix} }). You may want to instead use [...] or begin{equation}...end{equation}instead of $...$ since this looks like a display equation rather than an inline equation.

The fixed code compiles normally and has the expected result for me.

yes I know, I corrected the misplaced $ and got my desired outcome so my question no longer needs an answer

You could use the bsmallmatrix environment, provided by the mathtools package, to render the row and column vectors in the frac expression more compactly.

enter image description here

documentclass{article}

usepackage{mathtools}

begin{document}

[

begin{bmatrix}

  0 \ 0 \ 1 \ 1 

end{bmatrix}   

- frac{ 

begin{bsmallmatrix}

  0 & 0 & 1 & 1 

end{bsmallmatrix}  

begin{bsmallmatrix}

  1 \ 1 \ 1 \ 1 

end{bsmallmatrix}}{%

begin{bsmallmatrix}

  1 & 1 & 1 & 1 

end{bsmallmatrix}  

begin{bsmallmatrix}

  1 \ 1 \ 1 \ 1 

end{bsmallmatrix} }

begin{bmatrix}

  1 \ 1 \ 1 \ 1 

end{bmatrix}
