“Unless”

@Cammy, happy to help! Here are the steps to take when diagramming the word "unless": (#1) make the part of the statement directly following the word "unless" into the Necessary condition (#2) negate the other part of the statement and make it into the Sufficient condition For example, if we were told "A unless B," our diagram would look like: NOT A -> B. The first sentence of this passage states, "Unless the residents of Glen Hills band together, the proposal to rezone the city will be approved." Let's follow the steps described above to diagram this: #1) "the residents of Glen Hills band together" is the Necessary condition #2) NOT "the proposal to rezone the city will be approved" is the Sufficient condition This gives us: proposal NOT approved -> residents band together. The contrapositive is: residents NOT band together -> proposal approved Does that make sense? Please let us know if you have any other questions!

This is how I diagrammed it, however in the video explanation she makes unless the sufficient condition. I'm confused.

I am also confused on the same thing

I am confused as well. Why is there a discrepancy between how to diagram unless between what Skylar said and what the video states?

I think that once you get really good at translating S/N statements, your brain automatically translates between a positive and contrapositive at lightning speed and equates them in your mind. Then, when you're diagramming, you subconsciously choose the most suitable version and write it down. That's probably what's happening on the video. It's something to aspire to - hopefully, we will all be doing it with enough practice.
