The Collatz Conjecture is the simplest math problem no one can solve — it is easy enough for almost anyone to understand but notoriously difficult to solve. So what is the Collatz Conjecture and what makes it so difficult? Veritasium investigates.

## Why is 3x1 impossible?

The 3x+1 problem concerns an iterated function and the question of whether it always reaches 1 when starting from any positive integer. It is also known as the Collatz problem or the hailstone problem. . This leads to the sequence 3, 10, 5, 16, 4, 2, 1, 4, 2, 1, ... which indeed reaches 1.

## What is the hardest formula to solve?

Yet only one set of equations is considered so mathematically challenging that it's been chosen as one of seven “Millennium Prize Problems” endowed by the Clay Mathematics Institute with a \$1 million reward: the Navier-Stokes equations, which describe how fluids flow.

## What is the 3x 1 problem called?

"The 3x+1 problem, also known as the Collatz problem, the Syracuse problem, Kakutani's problem, Hasse's algorithm, and Ulam's problem, concerns the behavior of the iterates of the function which takes odd integers n to 3n+1 and even integers n to n/2.

## What's the most famous equation?

Kane and Morton M. Sternheim,' says: The equation E = Mc2 is perhaps the most famous equation of twentieth- century physics. It is a statement that mass and energy are two forms of the same thing, and that one can be converted into the other (ibid., p.

## How much is a dollar in math?

1 dollar = 100 cents, so 1 cent is equal to 0.01 dollars. 1 nickel = 5 cents, so 1 nickel is equal to 0.05 dollars. 1 dime = 10 cents, so 1 dime is equal to 0.1 dollars. 1 quarter = 25 cents, so 1 quarter is equal to 0.25 dollars.

## What's the answer to x3 y3 z3 K?

The equation x3+y3+z3=k is known as the sum of cubes problem. For decades, a math puzzle has stumped the smartest mathematicians in the world. x3+y3+z3=k, with k being all the numbers from one to 100, is a Diophantine equation that's sometimes known as "summing of three cubes." ∴ The required result will be 3xyz.

## What is the largest number in the world?

A "googol" is the number 1 followed by 100 zeroes. The biggest number with a name is a "googolplex," which is the number 1 followed by a googol zeroes.

## Who created math?

The earliest evidence of written mathematics dates back to the ancient Sumerians, who built the earliest civilization in Mesopotamia. They developed a complex system of metrology from 3000 BC.

## What's the hardest math question?

Today's mathematicians would probably agree that the Riemann Hypothesis is the most significant open problem in all of math. It's one of the seven Millennium Prize Problems, with \$1 million reward for its solution.

## What are the 6 hardest math problems?

Unsolved problems
• Birch and Swinnerton-Dyer conjecture.
• Hodge conjecture.
• Navier–Stokes existence and smoothness.
• P versus NP.
• Riemann hypothesis.
• Yang–Mills existence and mass gap.

## What is the E in math?

The term Euler's number (e) refers to a mathematical expression for the base of the natural logarithm. This is represented by a non-repeating number that never ends. The first few digits of Euler's number are 2.71828.

## What math should everyone know?

To do anything involving math, you will need to know how to add, subtract, multiply and divide basic numbers. Knowing these basics is extremely helpful, especially when dealing with money. For example: Addition: You and two co-workers pay \$5 each for a \$15 pizza: \$5 + \$5 + \$5 = \$15.

## What equation has not been solved yet?

The Collatz conjecture is one of the most famous unsolved mathematical problems, because it's so simple, you can explain it to a primary-school-aged kid, and they'll probably be intrigued enough to try and find the answer for themselves. So here's how it goes: pick a number, any number. If it's even, divide it by 2.

## What are the top 5 formulas in math?

Algebra
• Completing the square: x2+bx+c=(x+b2)2−b24+c.
• Quadratic formula: the roots of ax2+bx+c are −b±√b2−4ac2a.
• Circle: circumference=2πr, area=πr2.
• Sphere: vol=4πr3/3, surface area=4πr2.
• Cylinder: vol=πr2h, lateral area=2πrh, total surface area=2πrh+2πr2.

## Is there an odd perfect number?

While even perfect numbers are completely characterized, the existence or otherwise of odd perfect numbers is an open problem. We address that problem and prove that if a natural number is odd, then it's not perfect.

## Is 0 an integer?

As a whole number that can be written without a remainder, 0 classifies as an integer.

## Is it 16 or 1 math problem?

Some people got 16 as the answer, and some people got 1. The confusion has to do with the difference between modern and historic interpretations of the order of operations. The correct answer today is 16. An answer of 1 would have been correct 100 years ago.
