Three Navaho women sit side by side on the ground. The first woman, who is sitting on a goatskin, has a son who weighs 140 pounds. The second woman, who is sitting on a deerskin, has a son who weighs 160 pounds. The third woman, who weighs 300 pounds, is sitting on a hippopotamus skin. What famous geometric theorem does this symbolize?
The squaw on the hippopotamus is equal to the sons of the squaws on the other two hides.
An evil psychiatrist kidnaps an engineer, a chemist, and a mathematician to see how their minds work. He locks them in separate cells with a year supply of canned beans and leaves. When he comes back in a year to check on his prisoners, he finds:
The chemist had collected rainwater to corrode the cans of beans so he could eat them.
The engineer had taken apart his bed and made a crude can opener out of the parts.
The mathematician was slouched on the floor, long since dead. Written in blood beside the corpse read the following:
Theorem: If I don't eat the beans I will die.
Proof: Assume the opposite and seek a contradiction.
Two mathematicians went out to lunch. Over lunch, one complained that most people don't understand even basic maths. The other took a more optimistic view. A short time later, while the pessimist was in the bathroom, the other called the waitress over. "I am going to call you over in a few minutes," he explained, "and I am going to ask you a question. I want you to answer X3/3. OK?"....When the pessimist came back, he called the waitress over. "Look, I'll prove people understand math better than you think. OK, young lady, what is the integral of X2?"... "X3/3" she slowly repeated and walked away. Then she turned around and said, "Plus a constant."
A physicist had a horseshoe hanging on the door of his laboratory. His colleagues were surprised and asked whether he believed that it would bring luck to his experiments. He answered: "No, I don't believe in superstitions. But I have been told that it works even if you don't believe in it."
From A Random Walk In Science by R L Weber. It says this was one of Bohr's favorite stories.
An absent minded professor (alright, it was Norbert Weiner) was moving. His wife, knowing Norbert would forget his address, took out a sheet of paper and wrote it down for him. Later that day, Norbert had a flash of insight, and fumbling for a piece of paper, wrote down his new theorem on the paper his wife gave him. On further reflection, Norbert found a fallacy in this thinking and threw out the paper in disgust. When he came home that night, to the now empty house he moved from, he remembered he had moved, but had no idea where he had moved to. Just then he spied a little girl on the street. "Little girl," he asked, "my name is Norbert Weiner, do you know where I live now?" "Yes daddy, mommy thought you would forget."
Two Jews on a train in Russia. One asks the other, "Where are you going?" and the second one replies, "To Kiev." Whereupon the first says, "You liar, you tell me you are going to Kiev so I would think you are going to Odessa. But I know you are going to Kiev, so why do you lie?"
From Adventures of a Mathematician, Stan Ulam's autobiography (Pg. 143)
An airplane was flying to Poland. As it overflew a famous lake the captain come on the intercom, "If you look out to your right, you will see beautiful Lake Lek." Just then everyone went over to look at the lake and the plane crashed. Why?
Too many poles on the right side of the plane. Actually, in the version I heard, Lek Velenswa (you know who I mean?) was involved, but I just can't figure out how to spell it...
My friend Brad recently gots his Master's Degree in physics from the MIT. Unfortunately, he's having some trouble finding a job (it's tough to get a physics job these days). He's already spent two months looking for a job. He's running low on rent money so he decided to work in the Central Square McDonald's on weekends and look for a job during the week.
After Brad handed in an employment application, the manager told that he wasn't qualified. "Not qualified!?! I've got a Master's degree in Physics from MIT!" he said. The McDonald's manager replied, "I'm sorry, but all of our physicists have PhDs."
A physicist, an engineer and a mathematician are staying in a hotel when the engineer's bed catches fire. He goes outside, gets a fire extinguisher and puts it out. Then he goes back to sleep.
After a while the physicist's bed too catches fire. He goes outside, gets a fire extinguisher and puts it out. Then he too goes back to sleep.
The mathematician's bed then catches fire. He goes outside and sees the fire extinguisher. He thinks 'Ah, a solution exists' then goes back to bed.

This isn't really a maths question but quite a fun one.
ALBERT EINSTEIN'S RIDDLE
There are no tricks, just pure logic, so good luck and don't give up.
1. In a street there are five houses, painted five different colours.
2. In each house lives a person of different nationality
3. These five homeowners each drink a different kind of beverage, smoke different brand of cigar and keep a different pet.
THE QUESTION: WHO OWNS THE FISH?
HINTS
1. The Brit lives in a red house.
2. The Swede keeps dogs as pets.
3. The Dane drinks tea.
4. The Green house is next to, and on the left of the White house.
5. The owner of the Green house drinks coffee.
6. The person who smokes Pall Mall rears birds.
7. The owner of the Yellow house smokes Dunhill.

Answer delivered to you by Yogeshwar Gohil, I have checked it, and it is correct, and in the only way possible.

THE GERMAN PERSON OWNS THE LITTE FISHYWISHY ;)
Method:
This is the manner in which I was able to solve this riddle. It took me a while, but I am certain this is the only correct answer.
I drew a chart like this:
House 1
House 2
House 3
House 4
House 5
Color
Person
Drink
Smoke
Pet
And I also made a place for associations, those facts that are linked together but cannot yet go into the chart.
SO, the first time through the clues I came up with.
House 1
House 2
House 3
House 4
House 5
Color
Blue
Person
Norwegian
Drink
Milk
Smoke
Pet
Along with the following direct associations:
And with the following adjacent associations:
Brit  Red House
Swede  Dogs
Dane  Tea
Green House  Coffee
Pall Mall  Birds
Yellow House  Dunhill
Bluemasters  Beer
German  Prince
Green House on the left of White House
Blends next to Cats
Horse next to Dunhill
Blends next to Water
So analyzing these facts we can see more associations:
1. House 3 CANNOT be Green since the owner drinks Milk, not Coffee.
2. Thus House 4 MUST be Green since it requires a house to the right. One which is White.
3. House 1 CANNOT be Red since the Norwegian lives there.
These facts limit the house color order to ONE possible solution.
Combined with the direct associations we have...
House 1
House 2
House 3
House 4
House 5
Color
Yellow
Blue
Red
Green
White
Person
Norwegian
Brit
Drink
Milk
Coffee
Smoke
Dunhill
Pet
Along with the following direct associations:
And with the following adjacent associations:
Swede  Dogs
Dane  Tea
German  Prince
Pall Mall  Birds
Bluemasters  Beer
Blends next to Cats
Horse next to Dunhill
Blends next to Water
Now, looking for more limitations/associations we find that:
1. The Horse must be at House 2 since House 1 smokes Dunhill.
2. House 1 cannot have Birds, Dogs or Pall Mall.
3. House 3 cannot have Dogs, Bluemasters or Prince.
4. Either House 2 or 5 have the Bluemasters  Beer.
5. Since the horse is at House 2, then it must also have the Dane (the Swede has Dogs after all).
Our chart now looks like this, including the conditions "Dane  Tea" and "Swede  Dogs".
House 1
House 2
House 3
House 4
House 5
Color
Yellow
Blue
Red
Green
White
Person
Norwegian
Dane
Brit
German
Swede
Drink
Tea
Milk
Coffee
Beer
Smoke
Dunhill
Prince
Bluemasters
Pet
Horse
Dogs
Remaining limitations/conditions:
1. Pall Mall  Birds
2. Blends next to Cats
3. Blends next to Water.
1. House 3 MUST have "Pall Mall  Birds" (only house left without a smoke or pet defined).2. "Blends next to Cats" can now only fit with Blends at House 2 and Cats at House 1.3. The German is now the only one without a pet, therefore owns the fish.
4. Incidentally leaving the Water for the Norwegian.
House 1
House 2
House 3
House 4
House 5
Color
Yellow
Blue
Red
Green
White
Person
Norwegian
Dane
Brit
GERMAN
Sweed
Drink
Water
Tea
Milk
Coffee
Beer
Smoke
Dunhill
Blends
Pall Mall
Prince
Bluemasters
Pet
Cats
Horse
Birds
FISH
Dogs
If you followed this analysis closely, you will see that this IS the only possible solution.

A sphere has two sides. However they are actually onesided surfaces.
In a group of 23, there is a probability more than half that at least two people will have their birthday on the same day.
Among all shapes with the same perimeter, the circle has the largest area.
As with people, there are rational, irrational, perfect and complex numbers.
As in art, there are imaginary and surreal numbers.
The next sentence is true.
The previous sentence was false.
12+34+5+67+8+9=100 and there is at least one more representation of 100 with 9 consecutive numbers that has the 4 math operations in between.
You can cut any circle into 8 pieces with 3 lines!
A broken nondigital clock shows the right time twice a day.
The only triangle with rational sides and angles is an equilateral triangle.
The word 'fraction' hails from the Latin 'fractio' which means to break. However there are continuous fractions.
At any given time there are two people with exactly the same number of hairs in New York.
If you multiply 1089 by 9 you get 9801. It's reversed. This also works with 10989, 109989, 1099989...I think...
1 is the only positive whole number that you can add to 1,000,000 and you get an answer that's bigger than if you multiply it by 1,000,000
19 = 1 x 9 + 1 + 9 and 29 = 2 x 9 + 2 + 9. This also works for 39,49,59,69,79,89 and 99.
153, 370, 371 and 407 are all the "sum of the cubes of their digits". In other words 153=13+53+33
If you divide any square number by 8 you get a remainder of 0, 1 or 4
2 is the only number that gives the same result added to itself as it does times by itself
If you multiply 21978 by 4 it turns backwards
There are 12,988,816 different ways to cover a chess board with 32 dominoes.
Sixty nine squared = 692 = 4761 and sixty nine cubed = 693 = 328509. These two answers use all the digits from 0 to 9 between them.
You can chop a big lump of cheese into a maximum of 93 bits with 8 straight cuts
In the English language "forty" is the only number that has all its letters in alphabetical order.
1 ÷ 37 = 0·027027027... and 1 ÷ 27 = 0·037037037...
132 = 169 and if you write both numbers backwards you get 312 = 961.
This also works with 12 because 122 = 144 and 212 =441.
1/1089 = 0·00091827364554637281... (And the numbers in the 9 times table are 9,18,27,36...)
8 is the only cube that is 1 less than a square.
1274953680 has two odd things about it: it uses all the digits 09 AND you can divide it exactly by any number from 116.

THESE QUESTIONS DESERVE MERITS!
1>Expand the following:
(i) (2x + y + 2z)2 (ii) (x – 2y + z)2 (iii) (2p – 3q – r)2 (iv) (2a + 3b − 2c)2
2>Factorize: 6 x 5y^2 + 6 x 4y^3 + 9 x 2y^4 + 9 xy^5.
3>Hard problem:
Two pumps are used to fill a pool. First, pump A fills the pool in 12 hours and pump B fills the pool in 8 hours. There is a leak in the pool and the pool is empty in 24 hours. If both pumps are working together, how long does it take to refill the pool?
4>Hard Problem :
Simplify the algebra expression.
3(x  y) + 4(x  y 2) + 6.
SCROLL DOWN FOR ANSWERS. BUT TRY TO WORK IT OUR FIRST. THATS THE WAY TO DO IT.
AND IF YOU CAN ANSWER THESE QUESTIONS, ASK MR PITT FOR A MERIT :D IF YOU CAN ANSWER QUESTION 1, YOU ARE PROBABLY SMARTER THAN SOMEONE WHO CANT.
BY YOGESHWAR GOHIL AND Murshed Ahmed8J. CAN WE HAVE MERITS SIR???
1.Solution:
(i) (2x + y + 2z)2 = [(2x) + y + (2z)]2 = (2x)2 + y2 + (2z)2 + 2(2x)y + 2y(2z) + 2(2z)(2x)
= 4x2 + y2 + 4z2 + 4xy + 4yz + 8zx.
(ii) (x – 2y + z)2 = [x + (–2y) + z]2= x2 + (–2y)2 + z2 + 2x(–2y) +2 (–2y)z + 2zx
= x2 + 4y2 + z2 – 4xy – 4yz + 2zx.
(iii) (2p – 3q – r)2 = [(2p) + (–3q) + (–r)]2
= (2p)2 + (–3q)2 + (–r)2 + 2(2p) (–3q) + 2(–3q) (–r) + 2(–r)(2p).
= 4p2 + 9q2 + r2 – 12pq + 6qr – 4rp.
2.Solution:
Applying both step 1 and step 2, we have
6x5y2 + 6x4y3 + 9x2y4 + 9xy5 = 3xy2(2x4 + 2x3y + 3xy2 + 3y3)
3xy2 [(2x4 + 3xy2) + (2x3y + 3y3)]
3xy2 [x(2x3 + 3y2) + y(2x3 + 3y2)]
= 3xy2 (2x3 + 3y2) (x + y).
3.Solution:
In this hard algebra problem, the negative situation is taken for leakage. So subtraction operation is performed. Pump A is performing the work in 1 hour as th of a job and pump B is performing the job. The leakage is taken awayth of work.
In algebra form,+– = 1
Multiply the terms by 24.
2x + 3x – x = 24
5x – x = 24.
4x = 24
x =or 6
Therefore, the pool is filled in 6 hours.
4.Solution:
Given algebra expression is 3(x  y) + 4(x  y 2) + 6.
3x  3y + 4x  4y 8 + 6
7x  7y 2.
Therefore, the simplified algebra expression is 7x  7y 2.

Week 1
One day, a person went to horse racing area, Instead of counting the number of human and horses, he instead counted 74 heads and 196 legs. Yet he knew the number of humans and horses there. How did he do it, and how many humans and horses are there?
Week 2
Homer has to take Maggie, Santa's little helper, and rat poison across a river, However, Maggie, if left with the poison, will eat it and die, but if santa's little helper and maggie are together then they will fight over the toy. Homer can take just 2 of the above across the river at any one time and maggie will not eat the poison in homer's presence and maggie and santa's little helper wont fight.
Week 3
What is the area of a regular hexagon with sides 1 in. long?
Week 4
You have two block of clay in cube form and the edges are 10 cm. How many spheres with a radius of 5 cm can you make with that amount of clay?
Week 5
Every month, a girl gets allowance. Assume last year she had no money, and kept it up to now. Then she spends 1/2 of her money on clothes, then 1/3 of the remaining money on games, and then 1/4 of the remaining money on toys. After she bought all of that, she had $7777 left. Assuming she only gets money by allowance, how much money does she earn every month?

My Opinion On How Maths Came About edited The way I see it yh, humans understand things by naming them, categorizing them, or labeling them …(view changes)
The way I see it yh, humans understand things by naming them, categorizing them, or labeling them in a way that other folks can identify with. Math is just a way of organizing numbers. In the cave man days, it was probably as simple as trading two shiny stones for one big stick. If you had four shiny stones to begin with, you would understand you would only have two left after your transaction and all dat.
As people needed to count more and more, multiplication and division came into play just as a way to organize bigger and bigger numbers.
Algebra, Calculus and trig and all that geek stuff innit. but if you needed to deal with a number and you didn't know what that number was, you could substitute a letter. Angles and stuff play a big role in architecture and building. Formulas need to be thought of when making weapons, like, how much fuel does this missile need and at what rate will it be used in order to hit my target.
Math can be used to figure out at what rate the universe is expanding, where it will be in a million years, and where everything was a million years ago.
Overall, I'd say it was either made to help us better understand the universe and each problem that is solved makes more questions for us to evolve and figure out, Or it was invented by parents to keep kids busy doing homework after school so they would stop asking for toys. So basically innit yeah some guyz sick geezers innit counted da bling and got da dollarzzzzzzzzz and made happy, buff girls happy.

A mathematician is flying nonstop from Edmonton to Frankfurt with AirTransat. The scheduled flying time is nine hours.
Some time after taking off, the pilot announces that one engine had to be turned off due to mechanical failure: "Don't worry  we're safe. The only noticeable effect this will have for us is that our total flying time will be ten hours instead of nine."
A few hours into the flight, the pilot informs the passengers that another engine had to be turned off due to mechanical failure: "But don't worry  we're still safe. Only our flying time will go up to twelve hours."
Some time later, a third engine fails and has to be turned off. But the pilot reassures the passengers: "Don't worry  even with one engine, we're still perfectly safe. It just means that it will take sixteen hours total for this plane to arrive in Frankfurt."
The mathematician remarks to his fellow passengers: "If the last engine breaks down, too, then we'll be in the air for twentyfour hours altogether!"
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..."
Q: What does the zero say to the the eight?
