Five Nifty MATH Things about my Birthday
My birthday? 1/9/81.
I. If you remove the slashes, you get my birth year.
II. The month, day and year (two digit) are all powers of nine! (9^2=81, 9^1=9, 9^0=1)
II. In 2007, I had been alive 9497 days - which is a prime number. In 2008, I will have been alive 9862 days - which is TWICE a prime number (2x4931).
III. I share my birthday with Richard Nixon, a man who even math feared.
IV. 1+9+81 is 91 - the smallest non-trivial odd composite. (Every smaller odd composite is either a familiar square, ends in 5, has a digit sum that is a multiple of 3, or is obviously divisible by 11.) [Prime Curios!]
V. 1 divided 9 divided 81 is 0.00137174211248285. This number does not have meaning to me ... yet! ROCK
