#### Introduction

- Matrices can be added and subtracted to produce new matrices.
- This is only possible if the order (dimension) of the matrices is the same.
- To add (or subtract) two matrices, you add (or subtract) the corresponding elements.

#### Mathematical Definition

#### Example

#### code (Python)

```
import numpy as np
a = [[3, 6, 2], [5, 1, 10]]
b = [[7, 8, 1], [1, 5, 2]]
c = np.add(a, b)
print(c)
```
