When you add matrices, you simply add corresponding elements together. So, for the first problem, you can find the square by noticing that , which leads you to the answer of 3. Similarly, in the second matrix equation, just look at the top right corner: . Easy peasy!

To spice things up, remember that matrix operations are heavily used in computer graphics, physics simulations, and even in machine learning algorithms. They provide a powerful way to manipulate and transform data! Understanding how to work with matrices can open up a treasure chest of opportunities in various tech and science fields.
