Until yesterday I knew exactly 2 funny math jokes. Now I know three. Here’s the first one.
Two math professors are arguing in a cafe about the education level of the average person. One insists that the average person has little grasp of mathematics beyond arithmetic. The other asserts that the average person knows at least rudimentary calculus. They pass their lunch in fruitless debate.
Finally, the first professor goes to the bathroom. The second professor waves the waitress over. “I am having a bit of a debate with my friend here. When he returns, I’ll ask you a question. If you answer with the exact phrase ‘one third x cubed’, I’ll leave a ten dollar tip.”
“Ten bucks? You bet,” says the waitress.
The first professor returns. The second professor announces, “Here, I’ll prove it to you.” He turns to the waitress and asks, “What is the integral of x squared?”
“One third x cubed,” replies the waitress. They both laugh and the second professor leaves the $10 tip.
As they’re leaving, the waitress mutters, “…plus a constant.”
