A math student is pestered by a classmate who wants to copy his homework assignment. The student hesitates, not only because he thinks it's wrong, but also because he doesn't want to be sanctioned for aiding and abetting.
His classmate calms him down: "Nobody will be able to trace my homework to you: I'll be changing the names of all the constants and variables: a to b , x to y , and so on."
Not quite convinced, but eager to be left alone, the student hands his completed assignment to the classmate for copying.
After the deadline, the student asks: "Did you really change the names of all the variables?"
"Sure!" the classmate replies. "When you called a function f , I called it g ; when you called a variable x , I renamed it to y ; and when you were writing about the log of x +1, I called it the timber of x +1..."
Q: What does the zero say to the the eight?

The math professor just accepted a new position at a university in another city and has to move.
He and his wife pack all their belongings into cardboard boxes and have them shipped off to their new home. To sort out some family matters, the wife stays behind for a few more days while her husband has already left for their new residence.
The boxes arrive when the wife still hasn't rejoined her husband. When they talk on the phone in the evening, she asks him to count the boxes, just to make sure the movers didn't loose any of

them.
"Thirty nine boxes altogether", says the prof on the phone.
"That can't be", the wife exclaims. "The movers picked up forty boxes at our old place."
The prof counts once again, but again his count only reaches 39.
The next morning, the wife calls the moving company and complains. The company promises to check; a few hours later, someone calls back and reports that all forty boxes did arrive.
In the evening, when the prof and his wife are on the phone again, she asks: "I don't understand it. When you count, you get 39, and when they do, they get 40. That's more than strange..."
"Well", the prof says. "This is a cordless phone, so you can stay on the line and count with me: zero, one, two, three,..."

New York (CNN) . At John F. Kennedy International Airport today, a Caucasian male (later discovered to be a high school mathematics teacher) was arrested trying to board a flight while in possession of a compass, a protractor and a graphical calculator.
According to law enforcement officials, he is believed to have ties to the Al-Gebra network. He will be charged with carrying weapons of math instruction.
After her husband's death, the elderly lady decided to go back to school and get a degree in mathematics.
A few weeks into the term, she storms into the dean's office, exclaiming: "I've been silent until now - but I'm not going to take these obscenities anymore!"
"What obscenities are you talking about?"
She reaches into her purse and pulls out a notebook. "I noted of all of them. In my presence, professors had the complete lack of decency to speak of" - she leafs through her notebook -
"Bruhat-Tits spaces, a pumping lemma, and even degenerate colonels!"
Two mathematicians are studying a convergent series.
The first one says: "Do you realize that the series converges even when all the terms are made positive?"

Daughter: "Because I want to turn the table into a truth table!"
A mathematician and his best friend, an engineer, attend a public lecture on geometry in thirteendimensional space.
"How did you like it?" the mathematician wants to know after the talk.
"My head's spinning", the engineer confesses. "How can you develop any intuition for thirteendimensional space?"
"Well, it's not even difficult. All I do is visualize the situation in arbitrary N -dimensional space and then set N = 13."
A newlywed husband is discouraged by his wife's obsession with mathematics. Afraid of being second fiddle to her profession, he finally confronts her: "Do you love math more than me?"
"Of course not, dear - I love you much more!"

Happy, although sceptical, he challenges her: "Well, then prove it!"
Pondering a bit, she responds: "Ok... Let epsilon be greater than zero..."
"So how's your boyfriend doing, the math student?"
"Don't mention that crazy pervert to me anymore! We broke up."
"How can you say such a nasty thing about him? He seemed to be such a nice boy."
"Imagine! He was restless during the days and couldn't sleep at night - always trying to solve his math problems. When he had finally done it, he wasn't happy: he would call himself a complete idiot and throw all his notes into the garbage. One day, I couldn't take it anymore, and I told him to drop math. You know what he told me?"
"No."
"He said, he enjoyed it!!!"
It is only two weeks into the term that, in a calculus class, a student raises his hand and asks:

An American mathematician returns home from a conference in Moscow on real and complex analysis.
The immigration officer at the airport glances at his landing card and says: "So, your trip to
Russia was business related. What's the nature of your business?"
"I am a professor of mathematics."
"What kind of mathematics are you doing?"
The professor ponders for a split second, trying to come up with something that would sound specific enough without making the immigration officer suspicious, and replies: "I am an analyst."
The immigration officer nods with approval: "I think it's great that guys like you go to Russia to help those poor ex-commies to get their stock market on its feet..."
An investment firm is hiring mathematicians. After the first round of interviews, three hopeful recent graduates - a pure mathematician, an applied mathematician, and a graduate in mathematical finance - are asked what starting salary they are expecting.
The pure mathematician: "Would $30,000 be too much?"
The applied mathematician: "I think $60,000 would be OK."
The math finance person: "What about $300,000?"
The personnel officer is flabberghasted: "Do you know that we have a graduate in pure mathematics who is willing to do the same work for a tenth of what you are demanding!?"

"Well, I thought of $135,000 for me, $135,000 for you - and $30,000 for the pure mathematician who will do the work."
Statistics Canada is hiring mathematicians. Three recent graduates are invited for an interview: one has a degree in pure mathematics, another one in applied math, and the third one obtained his B.Sc. in statistics.
All three are asked the same question: "What is one third plus two thirds?"
The pure mathematician: "It's one."
The applied mathematician takes out his pocket calculator, punches in the numbers, and replies:
"It's 0.999999999."
The statistician: "What do you want it to be?"
A math professor, a native Texan, was asked by one of his students: "What is mathematics good for?"

In a speech to a gathering of mathematics professors from throughout the United States, George
W. Bush warned the academics not to misuse their position to force their often extremist political views on young Americans. "It is my understanding", the president said, "that you are frequently teaching algebra classes in which your students learn how to solve equations with the help of radicals. I can't say that I approve of that..."
To appreciate this joke, you may find it useful to check out some information on George W. Bush , the 43rd president of the United States of America.
Denis Diderot was a French philosopher in the 18 th
century. He traveled Europe extensively, and on his travels also stopped at the Russian court in St. Petersburg. His wit and suave charm soon drew a large following among the younger nobles at the court - and so did his atheist philosophy.
