**Matrix Multiplication Task:**
5. Review: Let matrices \( A \) and \( B \) be defined as follows:
\[
A = \begin{bmatrix} -1 & m \\ p & 4 \\ 3 & 0 \end{bmatrix}
\]
\[
B = \begin{bmatrix} 2 & -1 \\ 1 & n \\ 0 & 3 \end{bmatrix}
\]
- **Objective:** Compute \( A \times B \).
**Steps for Matrix Multiplication:**
1. **Confirm Matrix Dimensions:** Ensure that the number of columns in matrix \( A \) is equal to the number of rows in matrix \( B \).
2. **Perform the Multiplication:** For each element in the resulting matrix, use the dot product of the corresponding row of matrix \( A \) and column of matrix \( B \).
3. **Calculate Each Element:**
- For example, the element in the first row and first column of the resulting matrix is computed as:
\[
(-1) \times 2 + m \times 1 + 0 \times 0
\]
- Repeat for each element using the similar method.
**Ensure to calculate accurately**, keeping track of potential symbolic variables such as \( m \), \( p \), and \( n \).
- Review each step to confirm correctness before finalizing the answer.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F43bd6ecf-0a0f-4666-aaae-944e31ddf02f%2F0ce244ed-8d43-43bd-8a7b-4013fa434bd7%2Fhsc75c_processed.jpeg&w=3840&q=75)
