# Funny Math Proofs that will make you Laugh out Loud!

$\underline\text{Proof 1}$ : A proof that girls are evil (its a joke people, don't take offense)

Girls require time and money, so...

Girls = $\text{time} \times \text{money}$

Time is money, so...

Girls = $\text{money}^{2}$

Money is the root of all evil, so...

$\boxed{\text{Girls = Evil}}$

(Again, its a joke, don't kill me please)

$\underline\text{Proof 2}$ : Life is half happiness and half sadness(This is more insightful than funny)

Life + Love = Happiness

Adding the equations, and cancelling out +Love and -Love, we get...

$2 \times$ Life = Happiness + Sadness $\implies$ $\boxed{\text{Life} = \dfrac{\text{Happiness}}{2} + \dfrac{\text{Sadness}}{2}}$

$\underline\text{Proof 3}$ : Cats have nine lives, so why can't dogs have nine legs? (Kinda stupid, honestly)

No dog has 5 legs,

A dog has 4 more legs than no dog,

$\text{A dog has 4 + 5 = 9 legs}$

$\underline\text{Proof 4}$ : Pizza cylinder

A cylinder with radius $z$ and height $a$ has volume...

$\pi \times r^{2} \times h = \pi \times z^{2} \times a = \text{pizza}$ (PI x Z x Z x A is PIZZA, for those who didn't get it)

$\underline\text{Proof 5}$ : Se* = Fun $\implies$ (This is explicit...Sadly)

Let $f(a) = \sqrt[n]{e^{x}}$

Then...

\begin{aligned} \lim_{t \to \infty} f(a) - \dfrac{1}{f(t)} &= \dfrac{d}{dx} f(u) \\ \lim_{t \to \infty} f(a) - \dfrac{1}{\infty} &= \dfrac{d}{dx} f(u) \\ \lim_{t \to \infty} f(a) - 0 &= \dfrac{d}{dx} f(u) \\ \sqrt[n]{e^{x}} &= \dfrac{d}{dx} f(u) \\ \sqrt[n]{e^{x}}^{n} &= \dfrac{d}{dx} f(u)^{n} \\ \int \sqrt[n]{e^{x}} &= \int \dfrac{d}{dx} f(u) \\ \int e^{x} &= f(u)^{n} \end{aligned}

So, Se* = Fun.......(Sorry, but it is kinda funny. If you didn't get it, and are older than 13 years, think of the integral as an S)

$\underline\text{Proof 6}$ : Salary Theorem (Similiar to Proof 1)

Knowledge = Power

Time = Money

Power = Work/Time

Knowledge = Work/Time

Knowledge = Work/Money

Money = Work/Knowledge

As knowledge approaches 0, money becomes infinity, so it is safe to say that the richest people are quite dumb and to get a good salary, you must be dumb. (Don't tell Bill Gates or Jeff Bezos that I said that)

(I will add Latex to this proof later)

$\underline\text{Proof 7}$ : Flying Magnets are good to attract women (more instructions than proof)

If you need attractive women or girls to be attracted by you, do the following

• Hurl a magnet somewhere at the speed of light squared

• Throw in some useless variables like h, i and k.

• You have now got your very own, CHICK MAGNET!!!!!

LOL I love this one LOL

I will add more when I have the time, please suggest some funny proofs in the comments as well. Until then, Peace!

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

@Krishna Karthik, @Frisk Dreemurr - Why have you guys posted 10 messages and deleted them all? Need I remind you that is is annoying and frustrating :)

- 1 week, 5 days ago

idk srijan does that sometimes

- 1 week, 5 days ago

Ya, but Srijian is not here. I don't think he has seen this. I got 10-11 notifs from Krishna and Hamza all from this note, all deleted...

- 1 week, 5 days ago

just saying srijian does the same thing sometimes

- 1 week, 5 days ago

- 1 week, 5 days ago

yup

- 1 week, 4 days ago

@Frisk Dreemurr, @Nathan Soliman, @Krishna Karthik - A hilarious compilation of math proofs that are not math proofs lol

- 3 weeks, 5 days ago

Some say a jar is half full, some say it's half-empty. But I see it as a realistic cake.

- 3 weeks, 5 days ago

What's the joke, I don't get it.

- 3 weeks, 5 days ago

@Krishna Karthik - See Proof 5 lol

- 3 weeks, 4 days ago

@Percy Jackson Lol the last one was witty indeed. Btw theorem no 1 can be proved by the lemma "Bros before hos"

- 3 weeks, 4 days ago

I should show theorem no 5 to my business teacher and see what she says

- 3 weeks, 4 days ago

@Percy Jackson, I have another one: According to the law of "Schrödinger's cat", which is when you put and cat and a poisonous gas bottle into a box which you can't see inside, the cat is simultaneously both alive and dead in parallel universes, which made a funny theory:

C fro cat, A for alive, D for dead

C=A C=D A≠D

confusing right?

- 3 weeks, 4 days ago

Yeah. Literally everything quantum breaks the laws of classical physics. That's why quantum physics was invented.

- 3 weeks, 2 days ago

See Proof 7 @Krishna Karthik lol a real chick magnet lol

- 2 weeks, 5 days ago

@Percy Jackson check these out lol TROLL SIENCE

- 2 weeks, 5 days ago

LOL that is so cringy yet funny

- 2 weeks, 5 days ago

Hey Einstein, Percy Jackson broke your laws of Relativity

- 2 weeks, 5 days ago

Yes, I'm awesome :)

You can't throw something at the speed of light squared💡💡💡💡 but anyway my joke/proof

Rule of Topology:

• No cutting or gluing

How to turn a doughnut into a sphere:

Topologist: LOL you can't! ($\color{#D61F06} Wrong!!!$)

1. Get a doughnut

2. Nibble and bite at the doughnut (the rule says no cutting, not no nibbling and biting, and it's a doughnut, everyone wants to nibble at a doughnut, right?) until it becomes a banana shape

3. Stretch the banana shape into a sphere

4. Tell the topologists who go to your house to piss off

I am offended by the first proof LOL

Plus I don't need money, I need time

Oh wait

@Frisk Dreemurr Lol but I thought hos charge per hour?

Jk I'm kidding lol

- 1 week, 6 days ago

lol, Bros before hoes :)

- 1 week, 6 days ago

Ha, you should be lol. Its simple proof of bros before hoes! lol if you check urban dictionary for bros before hoes, you'll find this -

"A woman went out at night and came back next morning. Her husband asked here where she had been, and she said she was at a friend's place. The husband called up his wife's 10 best friends to ask if she had been to their places, and all of them said they had no idea where she was. Another night, the man went out, and came back next morning. When the wife asked him, he also said he'd been at a friend's house. The wife called 10 best friends of the husband, and 8 of them said that the husband had been to their houses. The other two said he was still there. Bros Before Hoes!"

# Why people who try to be inspirational say

you miss 100% of the shots you don't take

thats some dumb logic right there

- 1 week, 5 days ago

because when you don't do something, its almost always the same as doing it and being bad at it.

- 1 week, 5 days ago

@Nikolas Кraj - See proof 5. I think you will like it, based on your comments in my other problem.

- 1 week, 5 days ago

I saw this before you commented and indeed these are funny💣 I do not understand calculus but in my knowledge of math memes, integration of e^x is pointless yet you consider it as fun?

- 1 week, 5 days ago

Oh oooohhhh, the integral is the S, LOOL!!!😂😂

- 1 week, 5 days ago

yes lol

- 1 week, 5 days ago

Look at my note "Introduction to the new decade 2020 !" It's also funny, although I didn't expect 2020 to be this bad 🤷

- 1 week, 5 days ago

well, yeet :)

@Katniss Everdeen - Look at these :)

- 1 week, 3 days ago

Proof 1 - I might go Hunger Games on you for that...kidding bro, its cool

Proof 2 - Nice

Proof 3 - Stupidly hilarious

Proof 4 - Awesome

Proof 5 - You clearly didn't read my comment about me being 10 did you? I mean I understand the integration, but the end...seriously? Maybe you should put the 13+ warning before the proof, so that people can actually be warned before reading it? Other than your stupidity, its fine i guess...(I know what sex is, but I do not prefer using words like those, because, obviously, I'm 10)

Proof 6 - Surprisingly funny

Proof 7 - Your looks are the real chick magnet(coz you're Percy Freaking Jackson!), and also it violates the theory of relativity.

All in all, you are one heck of an amusing asshole Jackson...

- 1 week, 3 days ago

@Katniss Everdeen, it says in your profile that you are 16 lol

- 1 week, 3 days ago

Well, Katniss Everdeen's age at the end of Hunger Games is 16, that's why I also made my age 16.

- 1 week, 3 days ago

ok lol, just why people set their names to a book/game/film character?

- 1 week, 3 days ago

Dunno 'bout the other's but I just made my Profile all about Katniss because I didn't want to put my actual name, and didn't know if 10 was an allowed age on Brilliant.

- 1 week, 3 days ago

lol just saying, I accidentally found this website when I was doing my English assessment, just a tiny ad down in the corner.

- 1 week, 3 days ago

Ha lol. I found it as an ad when I was looking for Javascript codes to complete the game I was making.

- 1 week, 3 days ago

Javascript? Seriously? I am a JS programmer. Finally, someone else who knows Javascript!

- 5 days, 5 hours ago

I know JS too but that doesn't make me a (pro)grammer

- 4 days, 16 hours ago

Well, she clearly mentioned a game, so she must atleast have basic knowledge. Being a programmer doesn't mean having to be pro dude.

- 4 days, 4 hours ago

welp, sad me who only knows how to do scratch.

- 4 days, 4 hours ago

lol, scratch is like basic coding, everyone knows it lol

- 4 days, 4 hours ago

though, it is possible to make paper minecraft using scratch. lots of cool games actually can be made with scratch

Oh...um...oops, didn't know you were too young to actually be fine with seeing sexual words :)
