Two mathematicians walk into a bar. One is complaining about the state of mathematics education in America. ”The average person just doesn’t know any math,” she exclaimed with disgust.
The second mathematician said that he didn’t think things were so bad.
After they placed their drink order with the server, the man excused himself to use the restroom. Instead, he found the waitress and gave her $10. He said, “When you come to our table to deliver the drinks I’m going to ask you a question. I want you to answer ‘x squared.’ OK?”
He returned to the table and shortly afterward the waitress brought their drinks. The man turned to her and said, “Excuse me, we’re having a little disagreement. Can I ask you a question? What is the integral of 2x?”
The server made eye contact, smiled, and replied, “It is x squared…. plus c!”
