First, you do what’s in the parenthesis.
Second, you break down the exponent.
Third, you multiply or divide,
whichever comes first from left to right.
Fourth, you must add or subtract,
whichever comes first from left to right.
So, at this time, I ask for me,
Please excuse my dear aunt sally.

(verse1)
Benjamin Franklin invented bifocals
Bifocals or glasses, if you don’t know
Benjamin wanted to prove that lightning is electricity
So Benjamin conducted a famous kite experiment with a key
Benjamin helped to start America’s first library
He helped to put streetlights and paved roads in Philadelphia, the city
The Declaration of Independence was partly written by Benjamin
Benjamin also signed the United States Constitution
Benjamin Franklin was a scientist and an inventor
Benjamin Franklin was a writer and a leader
Benjamin Franklin’s face is on the hundred bill I spent
What Benjamin Franklin was not? He was not President
(chorus)
Benjamin Franklin
