Spacing issue between a paragraph and the tikzpicture diagram of Matricies - latex

Question

I've just learned how to use tikzpicture. Put when I trying to create a spacing between the paragraph and the diagram by using '\'. It didn't space properly even I used the wrapfigure method but the result is still the same.
Here's the picture and the code of the problem.
Problem 1
\textbf{\LSubtitle Step 1}
\\\\
Take the \underline{\textbf{1st column}} of the \textit{multiplier}, then, multiply with the \underline{\textbf{1st row}} of the \textit{multiplicand}.
\begin{wrapfigure}{b}{-1.3\textwidth}
\begin{tikzpicture}[>=latex]
\matrix (A) [matrix of math nodes,
nodes = {node style ge},
left delimiter = {[},
right delimiter = {]}] at (0,6*\myunit) %position (x,y). Higher number for x=going right,y=rise higher.
{
|[node style sp,red]| a_{11} & \ldots & \ldots & \ldots\\
|[node style sp,dark green]| a_{21} & \ldots & \ldots & \ldots\\
|[node style sp,blue]| a_{31} & \ldots & \ldots & \ldots\\
|[node style sp,black]| a_{41} & \ldots & \ldots & \ldots\\
};
\matrix (B) [matrix of math nodes,
nodes = {node style ge},
left delimiter = {[},
right delimiter = {]}] at (6*\myunit,6*\myunit)
{
|[node style sp,red]| b_{11} & |[node style sp,dark green]| b_{12} & |[node style sp,blue]| b_{13} & |[node style sp,black]| b_{14}\\
\ldots & \ldots & \ldots & \ldots\\
\ldots & \ldots & \ldots & \ldots\\
\ldots & \ldots & \ldots & \ldots\\
};
\draw[-,red](A-1-1) to[in=135,out=45]
(B-1-1);
\draw[-,green](A-2-1) to[in=135,out=45]
(B-1-2);
\draw[-,blue](A-3-1) to[in=135,out=45]
(B-1-3);
\draw[-,black](A-4-1) to[in=135,out=45]
(B-1-4);
\end{tikzpicture}\\\\\\
\end{wrapfigure}
