# Adding and subtracting matrices

### Adding and subtracting matrices

In this lesson, we will learn how to add and subtract matrices. We can only add or subtract matrices if their dimensions are the same. To add matrices, we simply add the corresponding matrix elements together. To subtract matrices, we simply subtract the corresponding matrix elements together. Not only can we add and subtract matrices, but we can solve matrix equations as well. For example, we can add or subtract both sides of the matrix equations to find out what the variable is.
