Matrix calculator and equation solver
Write what you want worked out, such as A*B + 2C or A^-1 * B, or a matrix equation such as A*X = B. The page asks for the size and entries of each matrix it finds, and gives the exact answer with the working.
Answer
3×3 matrix
| -24 | 18 | 5 |
| 20 | -15 | -4 |
| -5 | 4 | 1 |
Working
- A⁻¹ = [-24 18 5; 20 -15 -4; -5 4 1]
The matrices you gave
A =
| 1 | 2 | 3 |
| 0 | 1 | 4 |
| 5 | 6 | 0 |
