I don’t know if I’m familiar with that one. I’ll have to look it up. I actually had a student take a video in class when we felt like we had a way to explain dividing a positive by a negative. That is the one that I have not found a context/explanation that I think is intuitive and not something I have to memorize. It’s an issue with subtraction too but the Hot Air Ballons and Army men do well for that.
