Why 12,345?

Part of Keeping Your Squaring Arm Square

If you've done the math or worked with the spreadsheet, you found that the actual constant is 12,330.3. I turned it into 12,345 as a way to make the number easier to remember, but by doing so, I am introducing an error of about one ninth of one percent (well within the tolerances of this task). For some people the real question might be "What kind of person thinks this task is such an instrumental part of their lives that they need to commit this number to memory."
