If `A = [[3,4], [5,6]]` find `A+A^T`

If A=[[2, 3], [5, 7]] , find A+A^T .

If A=[[1,2],[3,-4],[5,6]] and B=[[4,5,6],[7,-8,2]] , is AB=BA? Also find AB and BA.

If A=[[2,4],[5,6]] , show that (A-A^T) is a skew symmetric matrix, where A^T is the transpose of matrix A.

If A=[(1,2),(3,4),(5,6)] and B=[(-3,-2),(1,-5),(4,3)] , then find D=[(p,q),(r,s),(t,u)] such that A+B-D=O .

If A(-3,4) ,B(5,6),then find point P on x-axis such that PA+PB is Minimum.

If A=[[2,3,-4],[1,0,6],[-2,1,5]],B=[[5,1,2],[6,-1,4],[5,3,-4]] , find 2A-3B .

Let A = { 2,3,5,7,9 } and B = { 2,3,4,5,6} Find A - B and B - A

If A={1,2,3},\ B={1,2,3,4},\ C={4,5,6},\ find : Axx(BnnC)

If A={1, 2, 3, 4, 5, 6} B={2, 4, 5, 6, 8, 9, 10}, "find" ADeltaB .

If A= [{:(,1,2),(,3,-4),(,5,6):}]and B=[{:(,4,5,6),(,7,-8,2):}] will AB be equal to BA. Also find AB & BA.
