Girl: Well, your worries are over.

The math teacher and the English teacher went out for a quick pizza after school.

“How long will the pizzas be?” asked the math teacher.

“Sorry, sir,” replied the waiter, “we don’t do long pizzas, just ordinary round ones.”

Fred: Yes, sir! The lesson that follows arithmetic.

In the summer vacation the math teacher collected information for a national opinion poll. But after a week she was fired. Her vital statistics were wrong.

Everyone tried to bring her 2.

A blind rabbit and a blind snake ran into each other on the road one day. The snake reached out, touched the rabbit and said, “You’re soft and fuzzy and have floppy ears. You must be a rabbit.” The rabbit reached out, touched the snake and said “You’re slimy, beady-eyed and low to the ground. You must be a math teacher.”

Philosophy is a game with objectives and no rules. Mathematics is a game with rules and no objectives.

Q: What do you get when you cross a sherpa and a mountain goat?

A: Nothing. you can’t cross two scalars.

Q: Did you hear that joke about the infinite line?

A: Don’t worry, It doesn’t have a point!

Q: Why did the two vectors start an internet-based company?

A: Because they thought they had a good dot product.

Q: Why did the number get mad at his wife?

A: Because she was being irrational.

A promising PhD candidate was presenting his thesis at his final examination. He proceeded with a derivation and ended up with something like:

F = -MA

He was embarrassed, his supervising professor was embarrassed, and the rest of the committee was embarrassed. The student coughed nervously and said “I seem to have made a slight error back there somewhere.”

One of the mathematicians on the committee replied dryly, “Either that or an odd number of them!”

A shoeseller meets a mathematician and complains that he does not know what size shoes to buy. “No problem,” says the mathematician, “there is a simple equation for that,” and he shows him the Gaussian normal distribution. The shoeseller stares some time at het equation and asks, “What is that symbol?” “That is the Greek letter pi.” “What is pi?” “That is the ratio between the circumference and the diameter of a circle.” Upon this the shoeseller cries out: “What does a circle have to do with shoes?!”

Why was the math book sad?

It had too many problems, and none of them could be solved with a magic wand!

Theorem: All positive integers are interesting.

Proof: Assume the contrary. Then there is a lowest non-interesting positive integer. But, hey, that’s pretty interesting! A contradiction.

The ark lands after The Flood. Noah lets all the animals out. Says, “Go and multiply.” Several months pass. Noah decides to check up on the animals. All are doing fine except a pair of snakes. “What’s the problem?” says Noah. “Cut down some trees and let us live there”, say the snakes. Noah follows their advice. Several more weeks pass. Noah checks on the snakes again. Lots of little snakes, everybody is happy. Noah asks, “Want to tell me how the trees helped?” “Certainly”, say the snakes. “We’re adders, and we need logs to multiply.”

What is “pi”?

Mathematician: Pi is thenumber expressing the relationship between the circumference of a circle and its diameter.

Physicist: Pi is 3.1415927plus or minus 0.00000005

Engineer: Pi is about 3.

The shortest math joke ever: let epsilon < 0 (*)

A biologist, a statistician and a mathematician are on a photo-safari in africa. They drive out on the savannah in their jeep, stop and scout the horizon with their binoculars.

The biologist : “Look! There’s a herd of zebras! And there, in the middle : A white zebra! It’s fantastic ! There are white zebra’s ! We’ll be famous !”

The statistician : “It’s not significant. We only know there’s one white zebra.”

The mathematician : “Actually, we only know there exists a zebra, which is white on one side.”

Q: What’s purple and commutes?

A: An abelian grape.

Q: What’s yellow, and equivalent to the Axiom of Choice?

A: Zorn’s Lemon.

Theorem : All positive integers are equal.

Proof :

Sufficient to show that for any two positive integers, A and B, A = B. Further, it is sufficient to show that for all N > 0, if A and B (positive integers) satisfy (MAX(A, B) = N) then A = B.

Proceed by induction.

If N = 1, then A and B, being positive integers, must both be 1. So A = B.

Assume that the theorem is true for some value k. Take A and B with MAX(A, B) = k+1. Then MAX((A-1), (B-1)) = k. And hence (A-1) = (B-1). Consequently, A = B.

What’s 72?

69 with 3 people watching!

Math jokes playfully explore the quirks and idiosyncrasies of mathematics, appealing to both math enthusiasts and those who might not be as fond of the subject. For example, “Why was six afraid of seven?” The answer is, “Because 7 8 (ate) 9!” This joke uses a simple numerical sequence to create a humorous scenario, making it accessible and funny to a wide audience. It’s a lighthearted way to engage with mathematics, turning numbers and operations into sources of amusement. Math jokes can make the subject more approachable by showing that even numbers can be part of a good laugh, breaking down barriers to learning and appreciation of math.
