Use :class:`.MathTex` to represent the matrices, try not to hardcode the values into the LaTeX string, instead, use python string formatting, this will allow us to define the resultant vector dynamically.
Use :class:`.MathTex` to represent the matrices, and try not to hardcode the values into the LaTeX string. Instead, you can use python string formatting and numpy vector addition, which will make it easier to change the vectors later if we need to.

To make sure the label of the vector and the vector shift together, you can define a custom :class:`.VGroup` class.
To make sure the label of the vector and the vector shift together, you can define a custom :class:`.VGroup` subclass.
Take a look at the decorator :meth:`override_animation` to override the :class:`.Create` and :class:`.Uncreate` animations, it will come in handy when animating the subclass.
