Kimihia te tau whakatau o te poukapa mā te whakamahi i te tikanga hauroki.
\left(\begin{matrix}4&1&-6&4&1\\1&-3&5&1&-3\\0&3&6&0&3\end{matrix}\right)
Whakaroatia te poukapa taketake mā te tāruarua i ngā tīwae tuatahi e rua hei tīwae tuawhā me te tuarima.

Tīmata atu i te tāurunga mauī o runga, whakareatia whakararo i ngā hauroki, ka tāpiri i ngā hua ka puta.
3\times 5\times 4+6=66
Tīmata atu i te tāurunga mauī o raro, whakareatia whakarunga i ngā hauroki, ka tāpiri i ngā hua ka puta.

Hei whakaroha mā ngā tauriki, me whakarea ia huānga o te haupae tuatahi ki tana tauriki, arā, ko te tau whakatau o te poukapa 2\times 2 i hangā mā te muku i te haupae me te tīwae i roto anō taua huānga, kātahi ka whakarea ki te tohu tūnga o taua huānga.
4\left(-3\times 6-3\times 5\right)-6-6\times 3
Mō te poukapa 2\times 2 \left(\begin{matrix}a&b\\c&d\end{matrix}\right), ko te ad-bc te tau whakatau.
4\left(-33\right)-6-6\times 3
Whakarūnātia.
