| This is the matrix I'm speaking of: 1 1 5
1 2 7
2 -1 4 Your online calculator doesn't seem to understand that this is an invertible matrix, why is that?

| If you try this in your computer: 1.0 - ( 1.0 / 3.0) - (2.0 / 3.0 ) you won't get 0 as expected. It is the same reason that causes this behavior in the calculator. We could of course use rounding in order to avoid it but then it would return erroneous results for near singular matrices.
