(X-Y) + (Y-1900) = 111 (X-Y) + (Y-1900) = ? X = Current Year ; Y = the Year you're born With (X-Y) we get our age, with (Y-1900) we get the last 2 digits, so you'll get 111 example: in my case, I born in 1978, I have 33 years so X=2011 ; Y=1978 (2011 - 1978) + (1978 - 1900) = 111 But if we take out the () from the formula, we get; X - Y + Y - 1900 = X - 1900 Once again, if X=2011 we get 2011-1900 = 111 .... there you get the 'Magical' 111 Reply
(X-Y) + (Y-1900) = ?

With (X-Y) we get our age, with (Y-1900) we get the last 2 digits, so you'll get 111
example: in my case, I born in 1978, I have 33 years so
X=2011 ; Y=1978
(2011 - 1978) + (1978 - 1900) = 111
But if we take out the () from the formula, we get; X - Y + Y - 1900 = X - 1900
Once again, if X=2011 we get 2011-1900 = 111 .... there you get the 'Magical' 111
