Mathematician Augustus de Morgan lived in the 19th century. He once said, "In the quadratic year of X, my age is X". What year was he born?
Set the year of birth to y
And then x? -y=x
y=x？ [Add to nouns in French etymology ending in -u to form plural]
the nineteenth century
So 1800
42*43= 1806
43*44= 1892
Obviously, when x=44, it is 1892+44= 1936 instead of19th century.
