This image contains a matrix exercise that involves matrix addition, subtraction, scalar multiplication, and transposition. The title mentions "Operasi Jumlah, Kurang pada Matriks," which translates to "Matrix Addition and Subtraction Operations."

It provides a set of matrices labeled $A$, $B$, $C$, $D$, $E$, $F$, $G$, $H$, $I$, $J$, $K$, and $L$. Below these matrices, 15 different matrix operations are listed, each requiring solutions based on combinations of the provided matrices.

Here are the first few operations:

1. $D + L + A$
2. $2A - \frac{3}{2} D + L$
3. $6B + 2I - 3H$
4. $\frac{1}{3} A^T + 5D - L$

Would you like me to compute any specific operation or explain how to solve one of these problems step by step?

If so, let me know which problem you'd like me to focus on.

Here are five relative questions for you to consider:

1. What is matrix transposition, and how does it affect a matrix?
2. How do scalar multiplications work with matrices?
3. What is the process for adding and subtracting matrices of different sizes?
4. What properties of matrices are maintained after addition or subtraction?
5. Can you identify the difference between symmetric and non-symmetric matrices?

Tip: Always ensure matrices are of the same dimension before performing addition or subtraction.
