Matrices

This week we learned how to do matrices. You can add, subtract, multiply, divide, square, cube... ect... matrices. They have other term that we learned to like transpose and trace. But today I am going to teach you how to add, subtract, and transpose matrices.

ADD:
1. You are going to add the first number in the first matrix to the first number in the second matrix.. you do this for the second, third, forth, and so on.. This rule applies the same for subtracting.
Example:
[1 2 [1 2 [2 4
3 4] + 3 4] = 6 8]
This is as easy as it gets.

2. Subtracting- do the same as adding but you subtract!
Example:
[1 2 [1 2 [0 0
3 4]- 3 4] = 0 0]
This is also as easy as it gets.

3. Transpose- when transposing you just make the row a column.
Example:
[1 2 3 4
5 6 7 8
9 9 9 9]

now transpose it.
[1 5 9
2 6 9
3 7 9
4 8 9]

** This are the easiest possible ways to add subtract and transpose matrices.
I hope you all got the hang of it, if not too bad cause you will officially be called an idiot.
