Part (b): It was quite challenging to make the video, as I wrote down the method in Textedit. I also had to type out a script, which took quite a while. We can write the workings blindly, but do we actually understand the question? By explaing the method through this activity, we gain a better understanding of what we are actually doing, as in Maths, it's not about memorizing, it's about the concept behind it.
