Camau gan Ddefnyddio Rheolau ar gyfer Matrics Rhifyddol

Gallwch ychwanegu neu dynnu dau fatrics dim ond os oes gan y ddau fatrics yr un nifer o resi a cholofnau.

$$\left(\begin{matrix}8&-6\\4&-2\\2&-5\end{matrix}\right)+\left(\begin{matrix}6&4\\-4&10\\0&2\end{matrix}\right)$$

I ychwanegu dau fatrics, ychwanegwch yr elfennau cyfatebol.

$$\left(\begin{matrix}8+6&-6+4\\4-4&-2+10\\2&-5+2\end{matrix}\right)$$
