Hi everyone!

So... I am watching the PT 61 LG section while FPing and I am having a little trouble understanding how JY got the contrapostive for R2 <—�> /U in the game. Can someone please clarify? Thank you so much!

    /U <---> R2 indicates a bi-conditional relationship. So you should review the lesson on Bi-Conditionals here: https://7sage.com/lesson/advanced-bi-conditionals/

    The 3rd rule says /U ---> R2, and the 4th rule says R2 --> /U. What is the contrapositive of each rule? /R2 ---> U and U --> /R2. So the contrapositive is U <---> /R2
