Let's add two 2 by 2 matrices step by step! 🎉 Imagine you have two groups of toys arranged in squares. Each square has some toys. We will add the toys in the same spots! **Box 1:** Add ➕ **Box 2:** = **Total box:** Step 1: Add top-left: $2 + 3 = 5$ Step 2: Add top-right: $2 + 1 = 3$ Step 3: Add bottom-left: $3 + 2 = 5$ Step 4: Add bottom-right: $1 + 4 = 5$ Great! The answer is $$\begin{bmatrix} 5 & 3 \\ 5 & 5 \end{bmatrix}$$ You did awesome adding matrices! 🎯
