Given `A=[(5//2,4),(6,3//2)]` and `B=[(1//2,2),(4,1//2)]`, Find A-B.

Explanation

To find \( A - B \), we will subtract the corresponding elements of matrix \( B \) from matrix \( A \).

Given:
\[ A = \begin{pmatrix} \frac{5}{2} & 4 \\ 6 & \frac{3}{2} \end{pmatrix}, \quad B = \begin{pmatrix} \frac{1}{2} & 2 \\ 4 & \frac{1}{2} \end{pmatrix} \]

### Step 1: Subtract the first element of \( B \) from the first element of \( A \)
