the correct answer is 9 . get behind that. after solving this u have to go back to the usual order like: 6÷2 = 3. and 3×3 is 9.
What is the answer to the Facebook math question?
By that convention, 6 ÷ 2(1+2) = 6 ÷ 2 × (1+2) = 6 ÷ 2 × 3 = 3 × 3 = 9 . If you were taking the ACT, SAT, or GRE (which would probably use parentheses to eliminate confusion), this method would yield the correct answer.
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.
What is the hardest math problem ever solved?
But those itching for their Good Will Hunting moment, the Guinness Book of Records puts Goldbach’s Conjecture as the current longest-standing maths problem, which has been around for 257 years. It states that every even number is the sum of two prime numbers: for example, 53 + 47 = 100. So far so simple.
What is the answer to the unsolvable math problem?
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.”
Why Bodmas is wrong?
Wrong answer
Its letters stand for Brackets, Order (meaning powers), Division, Multiplication, Addition, Subtraction. ... It contains no brackets, powers, division, or multiplication so we’ll follow BODMAS and do the addition followed by the subtraction : This is erroneous.

What is the longest equation?
What is the longest equation in the world? According to Sciencealert, the longest math equation contains around 200 terabytes of text. Called the Boolean Pythagorean Triples problem , it was first proposed by California-based mathematician Ronald Graham, back in the 1980s.
What is the easiest math equation in the world?
If by ‘simplest’ you mean easiest to explain, then it’s arguably the so-called ‘ Twin Prime Conjecture ‘. Even schoolchildren can understand it, but proving it has so far defeated the world’s best mathematicians. Prime numbers are the building blocks from which every whole number can be made.
Which country has toughest maths?
Which country has the hardest math? The United Kingdom, The United States of America, etc are the countries having one of the best education systems. But when it comes to having the hardest math, China and South Korea top the list.
What is the 1 million dollar math problem?
A correct solution to any of the problems results in a US$1 million prize being awarded by the institute to the discoverer(s). To date, the only Millennium Prize problem to have been solved is the Poincaré conjecture , which was solved in 2003 by the Russian mathematician Grigori Perelman. He declined the prize money.
What is the world’s hardest question?
- Science is based on the correspondence theory of truth, which claims that truth corresponds with facts and reality.
- Various philosophers have put forth substantive challenges to the truth claims made by science.
What are the 7 unsolvable math problems?
Clay “to increase and disseminate mathematical knowledge.” The seven problems, which were announced in 2000, are the Riemann hypothesis, P versus NP problem, Birch and Swinnerton-Dyer conjecture, Hodge conjecture, Navier-Stokes equation, Yang-Mills theory, and Poincaré conjecture.
Why is math difficult?
Math seems difficult because it takes time and energy . Many people don’t experience sufficient time to “get” math lessons, and they fall behind as the teacher moves on. Many move on to study more complex concepts with a shaky foundation. We often end up with a weak structure that is doomed to collapse at some point.
Who invented math?
Archimedes is known as the Father of Mathematics. Mathematics is one of the ancient sciences developed in time immemorial.
