What is the oldest unanswered math problem?

The oldest widely recognized unsolved problem might be related to perfect numbers, specifically whether any odd perfect numbers exist, a question dating back to ancient Greek mathematics. However, for stated problems, Goldbach's Conjecture (1742) is a strong contender, proposing every even integer > 2 is the sum of two primes, while problems like squaring the circle, though proven impossible, represent ancient challenges.

What is the oldest unsolved problem in math?

The "oldest" unsolved math problem depends on definition, but popular contenders include Odd Perfect Numbers, potentially dating back to ancient Greeks (2,000+ years old) asking if any odd number equals the sum of its proper divisors, and Goldbach's Conjecture, proposed in 1742, stating every even integer > 2 is the sum of two primes. While Goldbach's is more famous, the Odd Perfect Number problem might be the truly ancient one, with mathematicians unable to find one or prove they don't exist. 

What is the real answer to 8 2 2 2?

The answer is, when you've got this type of expression. or you've got the same operation to do, you start left to right. Which is why you should always do 8 divided by 2 first. And then you'll get four times four and 16. So 16 Is the right answer to this problem.

What is the oldest math riddle?

The oldest known mathematical puzzle dates from Archimedes, more than two millennia ago. It is, in fact, a dissection puzzle - and appears in a treaty known today as Archimedes' Stomachion (or Ostomachion, or Syntemachion), contained in a Palimpsest written over by an anonymous medieval scribe compiling prayers.

Why is 6174 a magic number in maths?

6174 is a magic number, known as Kaprekar's Constant, because any four-digit number (not all digits the same) eventually leads to it through a simple process: arrange digits largest to smallest, subtract the smallest from the largest, and repeat; you'll hit 6174 in at most seven steps, where it then stays, demonstrating a fascinating property of base-10 numbers and leading to a fixed point in this iteration.
 

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.

What is the world's toughest riddle?

There's no single "world's toughest riddle," as difficulty is subjective, but popular contenders include the complex web-based puzzle Notpron, the logic-based "Hardest Logic Puzzle Ever" (two guards, two doors), and famous lateral thinking ones like the Harvard riddle about turning polar bears white (the answer is snow/weather), while many viral "hard" riddles are simple wordplay, notes wikiHow, Business Insider, and FOX Sports AM 1340. 

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

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!

What is the missing number 2 5 8 11 14?

What is (!) in math?

In math, the exclamation mark (!) denotes the factorial, meaning you multiply a number by all positive whole numbers less than it, down to 1 (e.g., 4!=4×3×2×1=244 exclamation mark equals 4 cross 3 cross 2 cross 1 equals 244!=4×3×2×1=24). It's crucial in probability (permutations/combinations) and sequences, representing the number of ways to arrange items. Also, 0!0 exclamation mark0! is defined as 1. 

What does God think about math?

Starting at the beginning in Genesis 1, we see that God spoke light and creation—and the deeply rich mathematics behind it all—into existence. Mathematics, then, can be understood as a language God has graciously given us access to, allowing us to see a special way in which His glory is on display.
