Question
Evaluate the following:
`[[1 -1],[0 2],[2 3]]` `([[1 0 2],[2 0 1]]-[[0 1 2],[1 0 2]])`
Solution
`[[1 -1],[0 2],[2 3]]` `([[1 0 2],[2 0 1]]-[[0 1 2],[1 0 2]])`
`⇒[[1 -1],[0 2],[2 3]]` `[[1-0 0-1 2-2],[2-1 0-0 1-2]]`
`⇒[[1 -1],[0 2],[2 3]]` `[[1 -1 0],[1 0 -1]]`
`⇒[[1-1 -1+0 0+1],[0+2 0+0 0-2],[2+3 -2+0 0-3]]`
`⇒[[0 -1 1],[2 0 -2],[5 -2 -3]]`
