Poem: Thirteen, Good and Bad
A baker's dozen twelve plus one get an extra loaf avoid a flogging Thirteen disciples the last one a traitor therefore the number cursed forever A prime number and a 'happy' number* : each digit squared approaches one. Thirteen months in a Chinese leap year equally spaced twenty eight days each Card XIII rider on a pale horse symbolizing change not always literal death. Fear of the unknown the step beyond Twelve paralyzed in uncertainty or embrace it wholeheartedly ___ Math note * A "happy number" is a number that does this: Take the square of the digits (13 is 1 and 3.So 1²=1 and 3²=9) Add those two numbers together (1+9=10) Take those digits and add them together (digits are 1 and 0. So 1²+0²=1) A 'happy number' is a number whose squares of their digits are 1 A "sad" number is a number whose square of their digits (when the whole process is over, it might take a while) doesn't equal 1. So 13 is actually a 'happy number".
