You will get the most out of this video if you try the problems on your own first before watching me give the answer.

Omigoodness! Thank you so much for this! I am an English major with concentrations in creative writing and history. I'm currently taking a logic class for my degree and for self-enrichment. I have been doing really great in the class so far. I have been understanding logical fallacies, types of statements, and logical operators really well. Then I came to this. I have been trying to understand this for two days; my boyfriend, who is a programmer, helped me some. However, when I did the assignment, I made the lowest score I have made in this class. Then I went on youtube and I looked through a few videos. I soon realized that all the videos I could find were by men or AMAB individuals. I scrolled and scrolled. Then a bout of internalized sexism I didn't even know was there flared up. Is my fem brain incapable of understanding this concept? Is this why I have leaned to the humanities? And then, is this how women in STEM feel? Then, your first twenty seconds explained it so well. The men I watched were using examples and analogies. My humanities brain kept analyzing these examples excessively. Why is lighting a match necessary for a fire? There are other ways to light a fire. Why is being 35 necessary for being president? There are other rules and plus, it's a stupid rule that protects the conservative elite more often in their cling for power. In your video, you got straight to the point. You used such clear language! Sufficient: with a, b I understand now. I'm going to watch the rest of your video, and hopefully, things will continue to be comprehended. Thank you so much for posting! I hope you keep posting these instructionals.
