If `A=[(2,3,2),(4,3,1)] B=[(1,9),(0,1),(6,9)]` find `AB`

If A = [ ( 2,-1,1),(2,-3,5) ] , B = [(3,-3),(4,-1),(5,0)] , find AB.

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

If A = [(1,2),(3,-2),(-1,0)]and B = [(1,3,2),(4,-1,3)] then find the order of AB.

If A = [(0,1),(2,3),(1,-1)]and B = [(1,2,1),(2,1,0)] , then find (AB)^(-1)

If A=[[1,2,3]], B=[(-5,4,0),(0,2,-1),(1,-3,2)] then (A) AB=[(-2),(-1),(4)] (B) AB=[-2,-1,4] (C) AB=[4,-1,2] (D) AB=[(-5,4,0),(0,4,-2),(3,-9,6)]

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

If A=[[2,1,3],[4,1,0]] and B=[[1,-1],[0,2],[5,0]] find AB and BA.

Given A=[{:(2,4,0),(3,9,6):}] "and" B=[{:(1,4),(2,8),(1,3):}] , is (AB)=B'A'?

If A=[(2,1,1),(3,-1,0),(0,2,4)], B=[(9,7,-1),(3,5,4),(2,1,6)] and C=[(2,-4,3),(1,-1,0),(9,4,5)]. Varify associative law for matrix addition.
