Example Question #1 : How To Subtract 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 #2 : How To Subtract 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 #3 : How To Subtract Matrices
When subtracting matrices, subtracting component-wise.
Example Question #4 : How To Subtract Matrices
If , then what is the value of ?
Match each term from the first matrix with the corresponding number from the second matrix and subtract.
Each of the numbers in the matrix solution now corresponds to the letters, a through f. Add a (upper left) and f (lower right).
