Test whether the following matrices A and B are conformable for A + B, AB and BA and find their values when they are conformable :
`A={:((1,2),(0,1))and B={:((1,0),(0,1)):}`
`A={:[(2,3),(5,6),(7,8)]:}and B={:[(3,8,5),(2,1,1),(1,3,3)]:}`

Find, where possible, A + B, A - B, AB and BA stating with reasons, where the operations are not pssible, when A={:[(4,2,-1),(3,-7,1)]:}and B={:[(2,3),(-3,0),(-1,5)]:}

If A=[(2,3,-1),(7,8,5)] and B=[(1,0,1),(2,-4,-1)] then find A+B.

A=[(-1,3,0),(-7,2,8)],B=[(-5,0),(0,3),(1,-8)] . then AB

Find AB and BA if exists from the following matrices A and B: (i) A=[{:(2,3,-1),(0,1,2):}]and B=[{:(2,-6),(-4,0):}] (ii) A=[{:(1,2,3),(0,1,-2),(-1,0,-1):}]and B=[{:(0,0,2),(2,0,0),(0,2,0):}] (iii) A=[{:(0,3,4),(2,1,-2),(1,-3,-1):}]and B=[{:(2,1,3),(-1,0,-2):}]

Find AB and BA if exists from the following matrices A and B: (i) A=[{:(2,3,-1),(0,1,2):}]and B=[{:(2,-6),(-4,0):}] (ii) A=[{:(1,2,3),(0,1,-2),(-1,0,-1):}]and B=[{:(0,0,2),(2,0,0),(0,2,0):}] (iii) A=[{:(0,3,4),(2,1,-2),(1,-3,-1):}]and B=[{:(2,1,3),(-1,0,-2):}]

Determine the matrices A and B, where A+2B={:[(1,2,0),(6,-3,3),(-5,3,1)] and 2A-B={:[(2,-1,5),(2,-1,6),(0,1,2)]:} .

Given A=[{:(2,4,0),(3,9,6):}]andB=[{:(1,4),(2,8),(1,3):}] . Is (AB)'=B'A?

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