(10000*1.05^3)-1000*(1-~1.05^3)%0.053711.05 That is: 10000 dollars with three years interest applied to it (as if no payment had been made for three years), minus 20 times a single 1000 dollar payment which has also received 3 years interest on it.
Call it an early draft - we learn from our mistakes and people that dedicate themselves to learning pressure themselves by making a lot of mistakes. Each individual, of course, has their own priorities and areas of focus which guide what we take away from these experiences. And it's kind of embarrassing when we let other people have a glimpse into the process. But everyone does it, to one degree or another. (And this relates to why it's good to have someone with a financial career be presenting about financial issues. It's about focus and perspective as much as anything else.)
