 The sound quality made this lecture rather hard to understand, but the actual examples were superb! It was nice to hear some background, general information to introduce the concept and then see examples worked on to show how the concept could be applied.

The work was easy to follow. The video maker was difficult to hear throughout the entire video. I like that they presented two examples; however, in the second example they kept just writing 3 and not the square root of 3. It would have been helpful if they explained rationalizing and what it means.

I like that this video was systematic in that it shows a general form and then works out the examples using the general form that was given. I also like that is showed multiple examples for the concept it was showing. I think it would be helpful if there was a definition or some more explanations of "surds" before the examples begin.
