A long long time ago
I can still remember
how my math class used to make me snore
'cause every number we would meet
would terminate or just repeat
but maybe there were numbers that did more
but then my teacher said "I dare ya'"
to try to find the circle's area
despite my every action
I couldn't find a fraction
I can't remember if I cried
the more I tried or circumscribed
but something touched me deep inside
the day I learned of pi
oh pi, pi mathematical pi
twice eleven over seven is a mighty fine try
a good old fraction you may hope to supply
but the decimal expansion won't die
the decimal expansion won't die
pi, pi mathematical pi
3.141592653589
a good old fraction you may hope to define
but the decimal expansion won't die
