Penjelasan dengan langkah-langkah:

left[begin{array}{ccc}2&1\-3&4\end{array}right] ^{t}=left[begin{array}{ccc}2&-3\1&4\end{array}right]

Maka, Hasil dari a^t + 2B adalah :

left[begin{array}{ccc}2&-3\1&4\end{array}right] +2left[begin{array}{ccc}1&2\1&-1\end{array}right] \=left[begin{array}{ccc}2&-3\1&4\end{array}right] +left[begin{array}{ccc}2&4\2&-2\end{array}right] \=left[begin{array}{ccc}2+2&-3+4\1+2&4+(-2)\end{array}right] \=left[begin{array}{ccc}4&1\3&2\end{array}right]
