Math Jokes

No matter what I serve my guests, they seem to like my Math jokes best.


A mathematician and an engineer are sitting at a table drinking when a very beautiful woman walks in and sits down at the bar.

The mathematician sighs. "I'd like to talk to her, but first I have to cover half the distance between where we are and where she is, then half of the distance that remains, then half of that distance, and so on. The series is infinite. There'll always be some finite distance between us."

The engineer gets up and starts walking. "Ah, well, I figure I can get close enough for all practical purposes."


A mathematician is a device for turning coffee into theorems
... Alfréd Rényi


A topologist is a mathematician who can't tell the difference between a doughnut and a coffee mug.


Did you know that all numbers are interesting? What’s that? You don’t believe me? Well I have a proof. Suppose not every number is interesting. Then let n be the smallest uninteresting number. That’s a rather interesting property isn’t it?
... Ron Graham

Q: What is the difference between a mathematician and a philosopher?
A: The mathematician only needs paper, pencil, and a trash bin for his work - the philosopher can do without the trash bin...

Q: What is the difference between a Ph.D. in mathematics and a large pizza?
A: A large pizza can feed a family of four.

When the math professor's wife returns home from work, she finds an envelope on the living room table. She opens it and finds a letter from her husband:

My dearest wife,

We have been married for nearly thirty years, and I still love you as much as on the day I proposed. You must realize, however, that you are now 54 years old and no longer able to satisfy certain needs I still have. I very much hope that you are not hurt to learn that, while you're reading this, I'm in a hotel room with an 18-year-old freshman girl from my calculus class. I'll be home before midnight.

Your husband, who will never stop loving you.

When the professor returns from the hotel shortly before midnight, he also finds an envelope in the living room. He opens it and reads:

My beloved husband,

You may recall that you, too, are 54 years old and no longer able to satisfy certain needs I still have. I thus hope that you are not hurt to learn that, while you're reading this, I am in a hotel room with the 18-year-old pool boy.

Your loving wife.

P.S. As a mathematician, you are certainly aware of the fact that 18 goes into 54 many more times than 54 goes into 18. Therefore, don't stay up and wait for me.

Q. Why do mathematicians like national parks?

A. Because of the natural logs.

Q: Why didn’t Newton discover group theory?
A: Because he wasn’t Abel.

The integral of e raised to the power of x equals the function of u raised to the power of n.

(Write it out in notation to see the joke)

Did you really write it out? You didn't do that in your head? ;-)

True story:
A student walked into his discrete math class late and in order not to interrupt he put his late slip on the teacher's desk furtively without the teacher noticing. The teacher noticed the slip on his desk afterwards. He commented "I see you put this slip on my desk without me noticing. I guess that's why they call this class discrete mathematics."

There is a shipwreck, and the only three survivors are a Doctor, a Lawyer, and a Mathematician, in a rowboat.

After some time drifting about the seas, eventually they get get to talking and get to know each other. One day the doctor asks, "Is it better to have a wife or a girlfriend? I would say it's better to have a wife. I work long hard and emotional hours, and it's really great to have a caring wife who cooks great meals, cleans my clothes, and expertly manages our home and children."

The lawyer says, "I think it's better to have a girlfriend. I'm a Divorce Lawyer and the cost to the man in Divorce is so extreme I don't see where having a wife is worth the risk."

The mathematician says, "I think it's better to have both."

"What !?" say the doctor and lawyer. "Why?"

"Because," the mathematician says, "You can tell your wife you're working late, and your girlfriend you need to spend time with your family, which gives you more time to work on proving the Riemann Hypothesis !"

Steven, Thanks for the chuckle, You actually had a couple in there I had never seen/heard.

Forgot to share the one I put on Twitter the other day...
On This Day in Math
math joke from my 7 yr old nephew, "What did the "0" say to the "8"?

"Nice belt!"
his followup was the old
"seven ate nine"

Our friend Jerome Chauvet had this posted the original time I put this up, which I thought was great:

Another one, heard from a 11 years old boy, which is more about logic:

Me : That's wrong ! You schould write this instead.
Schoolboy : No!
Me : What does this means? Write the correct answer now!
Schoolboy: I said no!!!
Me : Why?
Schoolboy: Well, I've always been told that the more you have mistakes, the better you get... Since I want to become the best in Mathematics ever, I need to make many mistakes, so I do not correct them.

Hard to retort anything good after that...

Hi Steve,

Although I have always appreciated such humour, however as you know I’m not one to be principally guided by metrics, yet more so by qualitative considerations. Thus I’m more inspired by what philosophers have to tell us rather than mathematicians. Then there is the odd time when both happen to be the same and thus present the most starting of revelations ;-)

“Marriage is for women the commonest mode of livelihood, and the total amount of undesired sex endured by women is probably greater in marriage than in prostitution.”

-Bertrand Russell

Hi Steve,

Then at times I would have to admit that a pure humourist can render revelations which are greater than both mathematicians and philosophers :-)

“Go to Heaven for the climate, Hell for the company.”
-Mark Twain

“I don't like to commit myself about heaven and hell - you see, I have friends in both places. .”
-Mark Twain

And thus I came to realize what had Twain to be such a man of wisdom, as knowing only while on earth and in life can we enjoy the best of both worlds :-)

One I came up, who knows how original:
Q: Why did the mathematician go to the beach?
A: He wanted to be a tan gent.

Haha, thanks for the laugh, here's another one about engineers:

Two engineering students were walking across campus when one said, "Where did you get such a great bike?"

The second engineer replied, "Well, I was walking along yesterday minding my own business when a beautiful woman rode up on this bike. She threw the bike to the ground, took off all her clothes and said, "Take what you want."

The second engineer nodded approvingly, "Good choice; the clothes probably wouldn't have fit."

OMG, Your blog is so cool coz make me laugh over and over xD
Thanks you so much!

nice jokes :-) I did not write it on the paper lol

Corinne Friesen said...

Sad to say, I got - and enjoyed - these jokes. aeiiiii!

cool math games said...

Very cool math jokes!!

Horror Movies said...

Math is a funfull subject really love it. These math jokes compelled me to laugh. Very funny.

Funny Clips said...

I wanted to thank you for this great read!! I definitely enjoying every little bit of it I have you bookmarked to check out new stuff you post.

This works best written out as an equation, but it can be proved that;

the Integral of e to the x = Function of U to the n

Great math fun going on in here, love it!

Cool Math said...

Really very nice jokes on maths. To be an expert in Math, you have to be friend with math. Thats what I understand for math,
