Simple Online Matrix Calculator (2×2)
Phone users
NOTE: If you're on a phone, you can scroll any wide matrices on this page to the right or left to see the whole expression.
This matrix calculator allows you to enter your own 2×2 matrices and it will add and subtract them, find the matrix multiplication (in both directions) and the inverses for you.
It shows you the steps for obtaining the answers.
You can enter any number (not letters) between −99 and 99 into the matrix cells.
Output
Here are the results using the given numbers.
Our two matrices are:
| A = | 1 | 5 | ||
| −2 | −3 |
| and B = | −5 | −3 | ||
| 4 | −5 |
Matrix Addition
A + B
| = | 1 | 5 | ||
| −2 | −3 |
| + | −5 | −3 | ||
| 4 | −5 |
| = | −4 | 2 | ||
| 2 | −8 |
Subtracting a Matrix
A − B
| = | 1 | 5 | ||
| −2 | −3 |
| − | −5 | −3 | ||
| 4 | −5 |
| = | 6 | 8 | ||
| −6 | 2 |
Matrix Multiplication
In general, if
| X = | a | b | ||
| c | d |
| and Y = | e | f | ||
| g | h |
then the product of the matrices X and Y is given by:
XY
| = | a | b | ||
| c | d |
| e | f | ||
| g | h |
| = |
