#### Work Step by Step

Matrices are used to represent different sets of data surveys like people’s habits, types of smart phones they use, and other real-life surveying data.
For instance, the GDP of a nation can be calculated by using matrices.
In many scientific centers, matrices can be used for recording data for different experiments. In robotics, matrices are the basis for generic robot movements.
Ultimately, matrices can be seen as spreadsheets or databases, which are critical in computer science and science in general.
