While making this video, I realized that my knowledge of various topics in algebra had to be used in the making of this question. The question had to be used. e.g find an unknown in an equation. However, there are also some challenges I faced in the process of making this video. Examples include screen recording did not capture the whole screen, trimming was difficult and sometimes I said the wrong things and had to re-do the entire presentation.
