You can cut and paste things like

\flushleft
  x(u) = \begin{bmatrix}1 \\ 1 \\ 0 \end{bmatrix} \\
  y(i) = \begin{bmatrix}0 \\ 1 \\ 0 \end{bmatrix} \\
\centering\\
\flushleft
preference: p(u,i) = x^\intercal(u) * y(i)\\
\centering\\
\flushleft
min  \sum\limits_{u,i} (r(u,i) - p(u,i))^2 +  \lambda (||x(u)||^2 + ||y(i)||^2)
