If ` A=[(1,3),(4,2)],B=[(4,1),(-6,3)]`and `C=[(1,3),(0,-5)]`, then find `A+B+C`?

If A={:[(2,3),(4,1)]:},B={:[(9,5),(-6,1)]:}andC={:[(2,-6),(-3,1)]:} then find (A+B)+C.

If A=[(2,3,4),(-3,0,2)], B=[(3,-4,-5),(1,2,1)], C=[(5,-1,0),(7,0,3)], then find A+B+C.

If A={:[(1,7),(5,6)]:},B={:[(-3,2),(-1,5)]:}andC={:[(2,-3),(4,1)]:} , then find A(B+C) and AB+AC.

If A=[(-1,0,2),(3,1,4)], B=[(0,-2,5),(1,-3,1)] and C=[(1,-5,2),(6,0,-4)], then find (2A-3B+4C).

if A=[{:(1,2,3),(4,5,6):}]and B=[{:(-3,-2),(0,1),(-4,-5):}], then find AB and BA ,

if A=[{:(1,6),(2,4),(-3,5):}]B=[{:(3,4),(1,-2),(2,-1):}], then find a matrix C such that 2A-B+c=0

If A = [{:(2, -3), (4, 1):}], B = [{:(2, 3), (5, 0):}]" and " C = [{:(-1, 2),(0, 5):}] then find A(B + C).

Let A=[{:(2,4),(3,2):}],B=[{:(1,3),(-2,5):}]" and "C=[{:(-2,5),(3,4):}]. Find: (i) A+2B (ii) B-4C (iii) A-2B+3C
