I'm so stressful because Coq is deleting my parentheses. I tried to maintain my parentheses but everytime I try Coq delete those! Can you help me about this?

I am not quite sure which problem you are troubling with; would you please come to 301-554 today no later than 20:00?

I think it's a natural thing. Because + operator has left associativity, there is no need to write (a+b)+c, and a+b+c is just okay. I guess that coq did it automatically for neat viewing.

BTW try to focus on the lecture right now :-)

@jeehoonkang Well.. I found some way to accommodate with this phenomenon. Thank you!
