Using matrices to manipulate data: Pet store | Matrices | Precalculus | Khan Academy

Keep going! Check out the next lesson and practice what you’re learning:

In other videos, we saw how we can use matrices to represent real-world situations. Once we do that, we can also manipulate the matrices (using common matrix operations like addition, subtraction, and scalar multiplication) to reveal more information about the context. Here, we manipulate matrices that represent the inventory of dog food in a pet store chain.
