Given A=[(1//2,4),(2,3//2)] and B=[(5//2...

Given `A=[(1//2,4),(2,3//2)]` and `B=[(5//2,4),(1,1//2)]`, Find A-B.

Text Solution

Verified by Experts

Since A,B are of the same order `2xx2` . Therefore , addition of A and B is defined and is given by `A+B=[(1//2,4),(2,3//2)]+[(5//2,1),(4,1//2)]=[(1//2+5//2,4+1),(2+4,3//2+1//2)]=[(3,5),(6,2)]`
