Given the following matrices, what is the product of
When subtracting matrices, you want to subtract each corresponding cell.
Now solve for 
and 
When subtracting matrices, you want to subtract each corresponding cell.
Now solve for
Compare your answer with the correct one above
If 
, what is 
?
If
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:
Therefore,

Match each term from the first matrix with the corresponding number from the second matrix and subtract.
Simplify.
Each of the numbers in the matrix solution now corresponds to the letters, a through f. Add a (upper left) and f (lower right).
