# The worlds hardest math problem

Goldbach's Conjecture states that every even positive integer greater than 3 is the sum of two (not necessarily distinct) primes.In math, some of the world’s brightest minds have found bizarre and amazing patterns (and have even turned them into crop circles).Supported by much experimental evidence, this conjecture relates the number of points on an elliptic curve mod p to the rank of the group of rational points.So what makes Singapore so good at a subject with which America's students have routinely struggled?No one has succeeded in proving or disproving the validity of this conjecture in 257 years.The “conjecture” (or proposal) was established by Pierre de Fermat in 1937, who famously wrote in the margin of his book that he had proof, but just didn’t have the space to put in the detail.The country's math curriculum, which has a strong focus on logic-based problem solving, has been so successful that it's been adopted around the world, including in the U. According to the latest report from the Program for International Student Assessment (PISA)—an exam designed to measure the math, reading, and science proficiency of 15-year-olds globally—Singapore's math competency essentially outshines that of the rest of the world: Singapore scores highest in the PISA 2012 assessment of problem solving, with 562 points on the PISA proficiency scale. Singapore also has the highest number of top-performing students in problem solving: 29 percent of students reach proficiency Level 5 or 6 (the OECD average is 11 percent).We’re going to save you the trouble and tell you that Cheryl’s birthday is July 16 according to Singapore and Asian School Math Olympiads. Right answer: Quadrilateral None lateral10 What's a polygon with four unequal sides called? In their quest to solve some of the most challenging problems, these dedicated and talented young men and women — some immigrants, others U.write for professionals can is hers i importance many the write english best way to start.

- The prime number theorem determines the average distribution of the primes. The Riemann hypothesis tells us about the deviation from the average.
- In the past month, the world has been gripped by a series of maths. More Only 4 per cent of top students could answer this maths problem.
- As the world puzzles over Cheryl's birthday, we take a look back at the hardest spelling, grammar, maths and logic questions we've published.
- One word problem from a Singaporean school exam briefly became the talk. admitted that it was "a difficult question meant to sift out the better students.". math competency essentially outshines that of the rest of the world.

In fact, according to rumors, the problem was so addictive that the whiteboards in the offices of Google were filled with attempted solutions.
