To add two or more matrices, first make sure they are the same size then
add their corresponding elements

3. Matrix Addition
Let’s see the process step
by step

4. Matrix 1
First assume we are adding two matrices together.10 0
-4 5
Matrix 1 =
2 x 2
The first matrix let’s call Matrix 1

5. Matrix 1
It has two rows
10 0
-4 5
It has two columns
Row 1
Row 2
Column1
Column2

6. Matrix 2
-6 3
1 -7
Matrix 2 =
2 x 2
Now, let’s introduce another matrix and call it Matrix 2

7. Matrix 2
It also has two rows
-6 3
1 -7
and two columns
Row 1
Row 2
Column1
Column2

8. Matrix 2
Both have two rows
-6 3
1 -7
Row 1
Row 2
10 0
-4 5

9. Matrix 2
-6 3
1 -7Column1
Column210 0
-4 5
Both have
two
columns

10. Matrix Addition
Because both are the same size (i.e., they have the
same number of rows and columns) they can be added
together.

Matrix 1 + 2
Just add their corresponding elements (Elements in the same position)
