From 660 (V45 Q35) to 730 (V48 Q42) - Thanks Knewton! PART 1

March 2011 - Another day at work full of fire drills and low morale. I don't think I can take this anymore. I need a way out. April 2011 -Things haven't gotten much better. I swear, my IQ drops 20 points every time we have a team meeting. Yes, that puts me in negative IQ territory. Wait, I know what...


I was onboard with your answer at first, but think about this:

1) For 1, you can also pick 2, and D[x]-d[x] would = 0 (1-1)
2) For 2, you can also pick 2 as x (Largest odd divisor of 2 is 1, which would result in 3)
