I am currently studying pure mathematics and one of the topic is working out product of elemnetry matrix.(adsbygoogle = window.adsbygoogle || []).push({});

My original question in follow up exercise was to work out inverse of the matrix and I did following ( please see attached document) and thats exactly what the answer at the back of the book is. However when trying to work out a product of elementry matrices I am utterly confused as the explaination given doesnt make sense to me.

I know you apply same row operation but can someone please have a look at this and tell me bit more explicitly to help me understand this better as this is a very new topic to me

(PLEASE NOTE THIS IS NOT HOMEWORK HELP)
