Answer:
What is it?
Two matrices can be added together if and only if they have the same dimension. Their sum is obtained by summing each element of one matrix to the corresponding element of the other matrix.
How is it used?
The numbers in a matrix can represent data, and they can also represent mathematical equations. In many time-sensitive engineering applications, multiplying matrices can give quick but good approximations of much more complicated calculations.
How can I solve it?

Answer:
Look at this video at the Khan Academy: https://www.khanacademy.org/math/precalculus/x9e81a4f98389efdf:matrices/x9e81a4f98389efdf:adding-and-subtracting-matrices/a/adding-and-subtracting-matrices
Step-by-step explanation: Matrices are useful in solving multi-variable equations. They incorporate a process of various matrix manipulations that lead to the solutions that satisfy a series of equations. An example might involve two equations:
5x+7y=11
13x+17y=25
A 2X2 matirx can solve these equations.
