Yes.
First formula is the damage formula against you, where K is sometimes 0.5 for Last Stand, and b is blocking, which operates after last stand cuts the damage in half (and is not a constant 0 or 1, as some badges increase your block reduction). Given that I think I'm the only Paper Mario challenge runner in this group, I wasn't expecting people to recognize this formula (as nobody else had a reason to memorize the last stand mechanics).
Second formula is the multijump/multibonk formula. I wasn't sure if this was too obvious for the second clue, or if I needed to be semi-obvious due to the sheer number of people in this group who don't seem to have played Paper Mario....
