What is the hardest math equation ever?

There's no single "hardest" math equation, as difficulty depends on context (solved vs. unsolved, theory vs. application), but contenders include the Standard Model Lagrangian (physics complexity), the unsolved Riemann Hypothesis (number theory), and the Navier-Stokes equations (fluid dynamics, a Millennium Prize Problem), all representing deep, complex, or intractable mathematical challenges.

What is the hardest math equation?

For decades, a math puzzle has stumped the smartest mathematicians in the world. x 3+y 3+z 3=k, with k being all the numbers from one to 100, is a Diophantine equation that's sometimes known as "summing of three cubes."

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 is 0.08333333333 as a fraction?

Fraction = 1 / 12 = 0.0833333333333 | Desmos.

Is it 16 or 1 in PEMDAS?

PEMDAS can answer this question: when it comes to multiplication and division, you always work left to right. This means that you would indeed divide 8 by 2 before multiplying by 4. The correct answer is 16. Anyone who argues it's 1 is definitely wrong—and clearly isn't using PEMDAS correctly!

The Test That Terence Tao Aced at Age 7

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.

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

143. So, 143 stands for I Love You. This numeric code is popular because it's easy to remember and type out, especially in texts or social media posts.

What does ∑ mean in math?

In math, the capital sigma (Σ) means summation, telling you to add a series of terms; the lowercase sigma (σ) often represents standard deviation in statistics, measuring data spread, or other specific functions like the sum-of-divisors function. Sigma notation (Σ) provides a concise way to write long sums, like adding numbers from 1 to 100, using limits above and below the symbol to define the terms.
 

Is maths 100% correct?

The conclusion is that while mathematics (resp. logic) undoubtedly is more exact than any other science, it is not 100% exact. We cannot be 100% sure that a mathematical theorem holds; we just have good reasons to believe it. As any other science, mathematics is based on belief that its results are correct.

Why does .99999 equal 1?

0.999... (with infinite repeating nines) equals 1 because it represents the limit of a sequence getting infinitely close to 1, meaning there's no space between them on the number line; you can show this algebraically (let x = 0.999..., then 10x - x = 9, so 9x = 9, thus x=1) or by understanding that 0.999... is just another way to name the number 1, just as 1/3 is 0.333... 

Who solved the $1 million math problem then disappeared?

Science history: Russian mathematician quietly publishes paper — and solves one of the most famous unsolved conjectures in mathematics — Nov. 11, 2002. Mathematician Grigori Perelman solved the Poincaré conjecture, and then rejected the $1 million prize that came with it.

Should I guess b or c?

Most people (and tutors) tell students that, if they have no idea on a question, to just guess answer choice “C” — the middle answer on most multiple choice tests.

Can a "correct answer" be subjective?

A subjective assessment involves an evaluator's personal judgment or opinion to determine the quality of responses. There is no single correct answer, and these assessments often require critical thinking, creativity, and interpretation.

Does exact mean?

The "exact meaning" of a word or concept refers to its precise, strict, and fully accurate sense, leaving no room for approximation or error, like "the exact time" or "exact copy". It can also mean to demand something forcefully, like "to exact payment," drawing from its Latin root meaning "to drive out" or "to compel,". 

What is 1 ➗ 0 and why?

1 divided by 0 (1/0) is undefined in standard mathematics because it breaks the rules of arithmetic; it doesn't equal a number like infinity (though limits approach infinity) and leads to contradictions, as you can't group things into zero-sized groups to make one. Division is repeated subtraction or grouping, and asking "how many zeros make one" has no answer, as adding zero always gives zero, never one.
 

Is it PEMDAS or BODMAS answer?

BODMAS is an acronym and it stands for Bracket, Order, Division, Multiplication, Addition, and Subtraction. In certain regions, PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction) is used, which is the synonym of BODMAS.

What is the viral math problem?

Viral math problems, like 8 ÷ 2(2+2) or 6 ÷ 2(1+2), divide the internet over the order of operations (PEMDAS/BODMAS) due to ambiguous notation, with answers often debated as 1 or 16 (or 9) depending on whether multiplication (juxtaposition) is done before or after division when working left-to-right. Most mathematicians agree that following strict left-to-right for multiplication/division yields 16 (8÷2=4, 4×4=16) or 9 (6÷2=3, 3×3=9), but the ambiguity itself makes them popular tricks, with some suggesting better notation (like fractions) avoids confusion.
 

What's bigger, 7 16 or 1/2?

1/2 is bigger than 7/16, because 1/2 is the same as 8/16, and 8 is greater than 7. To compare, you can convert 1/2 to have the same denominator (16), making it 8/16; since 8/16 > 7/16, 1/2 is larger.
