Augustus De Morgan was alive during the nineteenth century
and once wrote, "I was x years old in the year x^2."
What was the year of his birth?
How do you even figure this out? Where do you even start?
If you're waiting for a magical "Squared-age Formula", better sit down.
I assume that he was born in the 1800's.
. . Hence: .x² > 1800
Care to try some numbers?
