Example Question #4 : Find The Difference Of Two Matrices
Given the following matrices, what is the product of and ?
When subtracting matrices, you want to subtract each corresponding cell.
Now solve for and
Example Question #14 : Other Matrices
If , what is ?
You can treat matrices just like you treat other members of an equation. Therefore, you can subtract the matrix
from both sides of the equation. This gives you:
Now, matrix subtraction is simple. You merely subtract each element, matching the correlative spaces with each other:
Then, you simplify:
Example Question #1 : How To Subtract Matrices
Subtracting (and adding) matrices is very easy! You merely need to do a 1-to-1 correspondence between members. So, we could rewrite:
Then, you merely have to simplify:
Example Question #2 : How To Subtract Matrices
When subtracting matrices, subtracting component-wise.
