Here are some.

Student: 3000!

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..."

hi mathgogocart

I especially liked the 'timber' joke.

It reminded me of a lesson I had many years ago.

True story.

I had given out a maths book which had the answers in the back. Good for conscientious students as they could check their own answers but obviously open to abuse.

The questions were:

(1) How many lines of symmetry does a rectangle have?

(2) What is the order of rotational symmetry of an equilateral triangle.

(3) Draw a shape that has no lines of symmetry but has rotational symmetry of order 2.

Here are the answers that one student wrote:

(1) **2** (2) **3** (3) **Show your answer to your teacher.**

I didnt get the e > 0! Joke

'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

'God exists because Mathematics is consistent, and the devil exists because we cannot prove it'

I'm not crazy, my mother had me tested.

Hi;

I did not get that one either.

It means that the mathematicians brain tends to 0...

Hey, I am not remotely considered a mathematician and I am insulted. So you see that joke does not only work on mathematicians. I give it a nine.

A: Because they have sine and cosine to get a tan and don't need the sun!

A woman in a bar tries to pick up a mathematician.

"How old, do you think, am I?" she asks coyly.

"Well - 18 by that fire in your eyes, 19 by that glow on your cheeks, 20 by that radiance of your face, and adding that up is something you can probably do for yourself..."

teacher: Did you parents help you with these homework problems?

Pupil: No I got them all wrong by myself !

Teacher, I can't solve this problem.

Any five year old should be able to solve this one.

No wonder I can't do it then, I'm nearly ten !
