Please specify the answer for each step when answering the question and draw a circle around it so that I can understand. If possible, write clearly for me if you write by hand so that I can understand. Thank you for understanding and I appreciate you.

**Determine if B is the Multiplicative Inverse of A**

Given matrices:

\[ A = \begin{bmatrix} -2 & 2 \\ -2 & 4 \end{bmatrix}, \quad B = \begin{bmatrix} -2 & -3 \\ -3 & 3 \end{bmatrix} \]

To check if B is the multiplicative inverse of A, calculate the matrix products AB and BA.

Matrix Multiplications:

- **AB**: Multiply matrix A by matrix B.
- **BA**: Multiply matrix B by matrix A.

Fill in the resulting matrices:

\[ AB = \square \]
\[ BA = \square \]

**Question:** Is B the multiplicative inverse of A?

- [ ] No
- [ ] Yes

To determine if B is the multiplicative inverse of A, both products AB and BA must equal the identity matrix:

\[ I = \begin{bmatrix} 1 & 0 \\ 0 & 1 \end{bmatrix} \]
