Dear Bangor Daily News:

Here is my math for the average unemployment, Dow and national debt figures, for the letter I'm about to send.

Merriam - Webster's says says a hyphen (-) between two dates means up to and including.

You can get 12 digit calculators at Family dollar for $5.

National Debt is for nominal (actual at the time?) dollars. Davemanuel.com shows national debt from 1791 - 2010 in both nominal and 2010 "real" dollars.

Funk & Wagnalls says to find a percentage relationship of one number (4) and another (16), divide the former by the latter and multiply by 100:

4 divided by 16 = 0.25 x 100 = 25% (4 is 25 percent of 16).
