The Adventures of Calculus Man

At one point in time Calculus Man was a normal little boy named. Then one day, some weird old man showed him a Calculus
book, ever since that day, at the age of 5, he was addicted to Calculus.

One day as Calculus Man was reading his Calculus books, he heard a distressed yell. Looking in the direction it came from he 
saw a young woman. He went over and asked her what was wrong. She looked at him and told him she was trying to find out what 
4+7-b(9-y)+32-x=7700y. Calculus Man looked at her and told her that he could figure it out for her.

He looked at the question and told her the answer after a minute of thinking. Now I cannot tell you the answer to this question
because I do not know the answer, only Calculus Man does.

And from that day on was known as Calculus Man because of his expertise in calculating so fast. He then started wearing a
cape and tights everywhere.
