### Viva Voce Stuff by Wang Yi Chieh

Reflections
I face challenges in making the keynote to allow the person watching the clip to understand what the question and my statements are about. I am not really a person into IT stuff so I face problems like that. Hence, I think I can seek helps from my friends when needed to teach me the best way to present information clearly.

I also faced challenges in talking in a simple manner to allow a person who is of Primary five standards to understand it. I think I can improve on that by explaining more things to my fellow friends or even try to teach them math when needed to bring my viva voce skills to greater heights.

1. Part (i):
You have explained clearly how the equation is formed.
However, instead of describing it as 'shifting', you should add on to describe how you 'shift' and why - to add "-3" to both sides of the equation so that the equation remains balanced yet you are able to 'remove' the numerical value on the LHS of the equation.

Part (ii): You have given the correct formula and also mentioned about substituting the x value into the equation to find the numerical values of length and breadth.
However, while the screen shows cm^2, you were reading it as cm^3. So, what's exactly the unit?
The unit should be read as "square cm" or "cubic cm".

Part (iii): You have explained that due to the conversion 1 m = 100, that's why divide it by "100x100". Good.
However, note that the numerical answer in the clip is incorrect. It should be 0.023m^2
