Top ten elementary algebra skills

What are the most important things to know about elementary algebra? This can be packaged in many ways as a look into the literature shows. In this video, by design, any geometry or multi-variable topics have here been left out and are planned to be included in an intermediate algebra part. Also, any topic which involve functions (like logs or trig functions) will be placed into intermediate algebra or pre-calculus. Avoiding any arithmetic (which comes before elementary algebra) and geometry (which is a parallel subject) and calculus (a subject building up on top of intermediate algebra) allows to focus on important elementary algebra parts: 1) Variables 2) Separation 3) Order of operation 4) Multiplying out 5) Factor expressions 6) Adding Fractions 7) Multiplying powers 8) Powers of powers 9) Linear equations 10) Quadratic equation Here are the slides [PDF] shown in the sky background of the video: https://people.math.harvard.edu/~knil... Here is the document, mentioned in the video, on the order of operation rule PEMDAS https://people.math.harvard.edu/~knil... Here is the website for a day-long "Adventure of teaching algebra" workshop from 2017 https://people.math.harvard.edu/~knil... At the end, the video concludes with some remarks about relations to other mathematical subjects or the classification of algebra into elementary, intermediate and advanced algebra. I wanted to have done this video already in the spring for Math E 320 (in an other format). It is presented now because it will also help with some technology related projects I'm working on. The subject of elementary algebra is important to me because I have observed during 35 years of teaching (and in particular the 22 years here) that elementary algebra skills are pivotal for success in college math courses. More than anything else. Struggling with basic algebra skills can have the effect that more advanced math subject like multivariable calculus can become painful. Owning good elementary algebra skills is like a lubricant for learning more. Struggling with basic algebra tasks is what an insect must feel when drowning in honey (math is a sweet seductive subject). On the research side, I myself am also interested in the elementary algebra of networks. This is mentioned at the very end. On the technology side, this is an experiment with chroma key, as well as a long distance exploration experiment with the DJI mini 3. I'm happy, how both these experiments worked out. I acknowledge some cartoon parts from Gonick's algebra book. Larry Gonick is a Harvard Math graduate who as been visiting Harvard a few years ago and I'm a big fan, especially now, in a time when humor is under attack, in particular in journalism or education. The praise is a bit of compensation for (I think still ``fair") use of some cartoons. Also, I have a hard time reading 1300 page books on elementary algebra. The topics stressed in the cartoon book are exactly what is needed in higher level math and the lack of these skills is precisely what makes many students feel like hitting a wall.
