Thanks for your excellent notes!

'Let's call the matrix on the right E as elimination matrix (or elementary matrix), and give it subscript E21 for making a zero in the resulting matrix at row 2, column 1.

The next step was twice the second row minus the third row:'

Should read: 'third row minus twice the second row'...I think!

Cheers
