Let `A={:[(sqrt(3),-1),(2+sqrt(3),1-sqrt(3))]:},B={:[(-sqrt(3),2),(2-sqrt(3),1+sqrt(3))]:}` Find A+B.

Explanation

To find the sum of the matrices \( A \) and \( B \), we will add the corresponding elements of each matrix.

Given:
\[ A = \begin{pmatrix} \sqrt{3} & -1 \\ 2 + \sqrt{3} & 1 - \sqrt{3} \end{pmatrix}, \quad B = \begin{pmatrix} -\sqrt{3} & 2 \\ 2 - \sqrt{3} & 1 + \sqrt{3} \end{pmatrix} \]

### Step 1: Add the corresponding elements of matrices \( A \) and \( B \)
