Question

Given the matrices `A=[(5,7),(-1,6), (3,-9)], B=[(8,3), (5,1), (4,4)], C=[(0,4),(-2,5), (7,-1)], D[(6,2), (9,0), (-3,0)]`, how do you find A+B?

Answer 1

`A+B=[(13,10),(4,7),(7,-5)].`

Explanation:

Since `A and B` both are `3xx2` matrices, `A+B` is defined and is

again a `3xx2` matrix, worked out as under by adding the

corresponding entries :-

`A+B=[(5+8,7+3),(-1+5,6+1),(3+4,-9+4)]`

`A+B=[(13,10),(4,7),(7,-5)].`
