Question

Add {-6 -2 2}+ {-3 2 1}

Answer 1

`\huge\boxed{\sf \left[\begin{array}{ccc}-9&0&3\end{array}\right] }`

Explanation:

`\sf = \left[\begin{array}{ccc}-6&-2&2\end{array}\right] + \left[\begin{array}{ccc}-3&2&1\end{array}\right] \\\\= \left[\begin{array}{ccc}-6+(-3)&-2+2&2+1\end{array}\right] \\\\= \left[\begin{array}{ccc}-6-3&0&3\end{array}\right] \\\\= \left[\begin{array}{ccc}-9&0&3\end{array}\right] \\\\\rule[225]{225}{2}`
