Therefore the zeros of the function are 7 and negative 6. Obviously, we can't have negative time, so we only take 7 as an answer. :P Actually the equation gives you (x-7)(x+6)=0.

Not surprising, really. Even those kids with a good command of "mid-level" math (like calc) often don't have the mindset to actually use it in the real world.

But yeah, the main one is that there's no calculus anywhere on that clock face. You could also nitpick that 3 times by (pi – 0.14) isn’t nine, it’s 9.00477796 (and so on).

There are no Calculus equations. The equation for the "7" spot is wrong, it equals 6, so there are two places for "6". Save your money. I can tell you are horrible at math.
