The following are the steps in finding the matrix B, if `B + ({:(2, 3), (4, 5):}) = ({:(5, 4), (3, 2):})`. Arrange them in sequential order.
(A) `therefore ({:(p, q), (r, s):}) + ({:(2, 3), (4, 5):}) = ({:(5, 4), (3, 2):})`
(B) Let ` B = ({:(p, q), (r, s):})`
(C) `({:(p+2, q+3), (r+4, s+5):}) = ({:(5, 4), (3, 2):})`
(D) ` P + 2 = 5, q + 3 = 4, r+ 4 = 3, s + 5 = 2`
`rArr p = 3, q = 1, r = -1, s = -3`
(E) `therefore B = ({:(3, 1), (-1, -3):})`
