Oh yeah.* Percents and ratios and estimating.* Man, I think I've
  used percents and ratios and estimating my whole life.* How many
  parts of this to that?* Even cooking is easier with ratios
  rather than measurements. And... money math.* Money math is...
  weird and not quite like school math.* Things don't balance out
  in money math in the same way yet they also still have to.* It's
  weird.* They say it's the same but it's not.
