Question
Evaluate the following:
`([[1 3],[-1 -4]]+[[3 -2],[-1 1]])[[1 3 5],[2 4 6]]`
Solution
`([[1 3],[-1 -4]]+[[3 -2],[-1 1]])[[1 3 5],[2 4 6]]`
`⇒([[1+3 3-2],[-1-1 -4+1]])``[[1 3 5],[2 4 6]]`
`⇒[[4 1],[-2 -3]] [[1 3 5],[2 4 6]]`
`⇒[[4+2 12+4 20+6],[-2-6 -6-12 -10-18]]`
`⇒ [[6 16 26],[-8 -18 -28]]`
