Really fun so far! I think I've got everything except W and maybe B. Is there possibly a mistake or inconsistency with W? I found a way to get [3]50 = 40-30, which feels close. (And [0.7419]50 = 40-30, which is arguably true, lol.)
I came to the comments hoping for commiseration on how hard W is, but I suppose I can live with the reassurance that it is in fact gettable. Maybe in a few hours I'll be ready to re-enter the equation trenches and stare at it again.
oh, good lord. I wasn't expecting that gur gjb jbhyq unir qvssrerag zrnavatf!
Now I have solved the final challenge, but it did require me to rethink my understanding in one case. (That might be a nudge in the right direction. Can nudge further on request, but I bet you'll get there. :-) )
