Precalculus with Limits

In Exercises 5 and 6, match the matrix property with the correct form. $A$, $B$, and $C$ are matrices of order and and are scalars.

(a) 1$A = A$
(b) $A + (B+C) = (A+B) + C$
(c) $(c+d)A = cA + dA$
(d) $(cd)A = c(dA)$
(e) $A + B = B +A$

(i) Distributive Property
(ii) Commutative Property of Matrix Addition
(iii) Scalar Identity Property
(iv) Associative Property of Matrix Addition
