**Matrix Trace Calculation**

**Problem Statement:**
Find the trace of the matrix.

**Matrix \( A \):**
\[ A = \begin{bmatrix} -3 & 3 \\ 2 & -2 \end{bmatrix} \]

**Trace Formula:**
The trace of a matrix, denoted as \( \text{tr}(A) \), is the sum of the elements on the main diagonal.

**Calculation:**
\[
\text{tr}(A) = (-3) + (-2)
\]

**Result:**
\[
\text{tr}(A) = 
\]
