The empty set is better than nothing.

The Dad followup: No! Nothing is better than the empty set!

Q: What kind of jokes do constructivists love to tell?

A: Not not jokes.

A (classical!) logician becomes a father. “Congratulations! Is it a boy or a girl?” his friends ask him. He replies: “Yes.”

"Mathematicians like to repeat: 'Anagram is an anagram of anagram'. Gives them the sense of group identity".

Infinitely many people walk into a bar. The first asks for half a glass of whisky, the second for a quarter and so on. The bartender pours a single glass. Some of the customers complain, and the bartender throws them out, saying: you have to know your limits

An engineer and a mathematician share an office. One day, their shared wastebin catches fire, and the engineer pours his coffee on it, putting it out. The next week, the engineer is on vacation, and the wastebin catches fire again.

The mathematician goes to the kitchen, gets a cup of coffee, announces, “a solution exists!” and goes back to work.

I hate negative numbers. I will stop at nothing to avoid them.

One straight line meets another and says: “Next time we meet, beer is on me.”

A few functions are chilling at a pub. Suddenly, there’s panic: “Quick, hide! The derivatives are coming!” “I’ve nothing to worry about!” says e^x. “Nice try!” says d/dy.

B: Why can't people just be normal?

did you know 10+10 and 11+11 are the same thing???

10+10 is 20 and 11+11 is 20 too

I will do algebra and number theory but graphing geometric shapes is where I draw the line.

The applications of differential geometry are manifold.

What do you get if you put root beer in a square glass? Beer.

i might be irrational, but i² can get real!

There are three types of mathematicians: Those who can count and those who can’t.
