Hello, semi-aut-normie here. The yellow highlighted in no way explains what you are doing to get the numbers 7,6,5,4,3,2,1. The arrows are not helping. Suggestion- Take one set and show your work as you would in middle school. The more you show, the more credit you get. After that you can take shortcuts, because past proves future too… you know like geometry class… show your proofs… name your proofs… define your proofs… then you can meme the names of your proofs…
i.e. When writing your own two-column proof, keep these things in mind:
-Number each step.
-Start with the given information.
-Statements with the same reason can be combined into one step. …
-Draw a picture and mark it with the given information.
-You must have a reason for EVERY statement.
