I had to squint to see the numbers because of the fuzzy video, but I loved the clear, simple explanation. I only watched it once and I’ll be able to do the question. Good job guys.

I also understood this problem but unfortunately couldn’t see the numbers and work that you were showing. If you had done it on a blackboard or something, I think it would have turned out much better. But other than that, it was also very well explained and I understood the problem. Good job and now I can solve another part C question with ease.

wow u explained that really well, my only advice is that u should have zoomed in or written bigger =P cause it was kinda hard to read.=)

Really easy to understand, great use of logic. Music at the end kind of lightened the atmosphere, but overall great explanation.

Other than the blurry numbers, I think the question was nicely explained and I understand how it works. Way to go

Susan, Amar, Prab, Yushen, Kelvin. Five comments and not a single person has mentioned anything about the MATHEMATICS of this problem. I am looking for evidence that the video has made you think about something SPECIFIC to the question.

Good reasoning behind how to eliminate -2 and -4 from the line up. Very clear; very simple.

i thought it was smart of you guys to use even exponents to eliminate the negative numbers to keep the sum as large as possible, it makes the question a lot easier =D
