What's the hardest math question ever in the world?

There's no single "hardest" math question, but the Riemann Hypothesis is often cited as the most important unsolved problem, linked to prime numbers and offering a million-dollar prize; other contenders for hardest include the P vs. NP Problem, the Navier-Stokes Existence and Smoothness problem (both Millennium Prize Problems), and simpler-to-state but tough problems like the Collatz Conjecture. These questions challenge experts and have profound implications for mathematics and technology.

Will 3x-1 ever be solved?

The 3x + 1 problem or Collatz Conjecture, also known as the 3n + 1 problem, is a famous unsolved problem in mathematics that has puzzled mathematicians for over half a century. The problem is deceptively simple to state, but it has resisted all attempts to solve it.

What does ∑ mean in math?

In math, the uppercase sigma (Σ) means summation, a shorthand for adding a series of terms following a pattern, with limits (start/end values) indicated above and below the symbol. The lowercase sigma (σ) commonly represents standard deviation in statistics, measuring data spread, or is used in various other contexts like number theory (divisor functions) or logic.
 

What defines a "correct" answer?

A 'correct answer' is defined as a response that accurately reflects the right solution to a question, contributing to the total score in a testing scenario, as exemplified by the calculation of maximum possible correct answers in a group of questions.

The Man Who Almost Broke Math (And Himself...) - Axiom of Choice

Is 0.67 the same as 2/3?

You simply have to do the math. 2/3 becomes a decimal if you actually divide 2 by 3. The result will be 0.666, so about 0.67. Now, if you want to go the opposite way, knowing the place values becomes important.

What is the math code for "I love you"?

Saying "I love you" with math involves numeric codes like 143 (1 letter 'I', 4 'love', 3 'you'), programming snippets that print the phrase, or complex graphing equations that draw a heart, showing love through numbers, code, or visual patterns. Other creative ways include calculator tricks (typing 71077345 and flipping), using the Golden Ratio (φ), or symbolic equations like 3sin(x)−2sin(2x)+sin(3x)=03 sine x minus 2 sine 2 x plus sine 3 x equals 03sin(𝑥)−2sin(2𝑥)+sin(3𝑥)=0. 

What is 1 ➗ 0 and why?

As much as we would like to have an answer for "what's 1 divided by 0?" it's sadly impossible to have an answer. The reason, in short, is that whatever we may answer, we will then have to agree that that answer times 0 equals to 1, and that cannot be ​true, because anything times 0 is 0.

Is BODMAS or PEMDAS correct?

Neither PEMDAS nor BODMAS is inherently "more" correct; they are different acronyms for the same universally accepted order of operations, just using different terminology (Parentheses vs. Brackets, Exponents vs. Orders/Indices), with the crucial understanding that Multiplication/Division and Addition/Subtraction are performed from left to right as a single step. Both ensure consistent results by prioritizing Parentheses/Brackets, then Exponents/Orders, and finally Multiplication/Division (left-to-right), followed by Addition/Subtraction (left-to-right).
 

What is the answer to 11 11x11 11 only for genius?

-99 (PE)MDAS 11-11x11+11= Multiplication (11x11) = 11-121+11 ̶̶D̶̶i̶̶v̶̶i̶̶s̶̶i̶̶o̶̶n (yes, Pemdas. So the Multiplication and Division can change, And so does addition and subtraction, as its left to right.) Subtraction (11-121) =-110+11 Addition (-110+11) =-99 Therefore the answer is -99.

Who solved the $1 million math problem then disappeared?

The Russian mathematician Grigori Perelman solved the Poincaré Conjecture, one of the Clay Mathematics Institute's Millennium Prize Problems, earning him a $1 million reward, which he famously refused, along with a Fields Medal. After publishing his proof online around 2003, he rejected the accolades and prizes, citing disillusionment with the math community and a desire for privacy, and subsequently withdrew from mathematics and public life, living reclusively in St. Petersburg.
 

What are the 7 1 million dollar math problems?

The Clay Mathematics Institute officially designated the title Millennium Problem for the seven unsolved mathematical problems, the Birch and Swinnerton-Dyer conjecture, Hodge conjecture, Navier–Stokes existence and smoothness, P versus NP problem, Riemann hypothesis, Yang–Mills existence and mass gap, and the Poincaré ...

How much is 1 ⁄ 3 cup?

One-third of a cup (1/3 cup) in US measurements is 5 tablespoons plus 1 teaspoon, or approximately 2.67 fluid ounces (80 ml), which is a useful conversion when you don't have a 1/3 cup measure, as 1 cup equals 16 tablespoons. 

What is 0.6666666667 as a fraction?

The fraction represented by the decimal 0.666666666667 is 2/3.

Should I guess b or c?

For a blind guess on a multiple-choice test, picking one letter (like B or C) and sticking with it every time is a solid strategy, as it statistically increases your chances over random switching, though C is a popular choice due to perceived test-maker bias, but B might also be favored depending on the test. A better approach, if possible, is to eliminate obviously wrong answers first to improve your odds from 25% to 50%, then pick your consistent letter (B or C).
 

Can a "correct answer" be subjective?

In brief, subjective measurement involves more than one correct answer and assesses qualitative or analytic thinking. On the other hand, objective measurement is conducted independent of opinion.

Is it a or an answer?

You should use a when the word that follows sounds like it begins with a consonant ('a dog,' 'a balloon'). You should use an if the word that follows sounds like it begins with a vowel ('an ant,' 'an elevator').

Which number logically follows this series 4 69 6 14 6 answer?

Answer and Explanation:

= 6 a 3 = 4 + 5 = 9 a 5 = 9 + 5 = 14 a 7 = 14 + 5 = 19 So, the series becomes 4 , 6 , 9 , 6 , 14 , 6 , 19 , 6 , 24 , 6 , . . . Hence, 19 is the next number.
