Practice problem
Let A=[123456].A=\begin{bmatrix}1&2&3\\4&5&6\end{bmatrix}.A=[142536].
What would the matrix BBB look like if A+B=OA+B=OA+B=O?
[−1−2−3−4−5−6]\begin{bmatrix}-1&-2&-3\\-4&-5&-6\end{bmatrix}[−1−4−2−5−3−6]
[−1−2−3−4−5−6]\begin{bmatrix}-1&-2\\-3&-4\\-5&-6\end{bmatrix}−1−3−5−2−4−6
[000000]\begin{bmatrix}0&0&0\\0&0&0\end{bmatrix}[000000]
None of the above.
Type a concept, like “slope” or “photosynthesis”.
