## Which is the hardest math problem in the world?

The longest-standing unresolved problem in the world was Fermat’s Last Theorem, which remained unproven for 365 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.

## What are the hardest unsolved math problems?

**What is Kiss chemistry?**

Kissing causes a chemical reaction in your brain, including a burst of the hormone oxytocin. It’s often referred to as the “love hormone,” because it stirs up feelings of affection and attachment. According to a 2013 study, oxytocin is particularly important in helping men bond with a partner and stay monogamous.

### Is infinity odd or even?

I explained that infinity is neither even nor odd. It’s not a number in the usual sense, and it doesn’t obey the rules of arithmetic. All sorts of contradictions would follow if it did. For instance, “if infinity were odd, 2 times infinity would be even.

### What are the 6 unsolved math problems?

Birch and Swinnerton-Dyer conjecture. The Birch and Swinnerton-Dyer conjecture deals with certain types of equations: those defining elliptic curves over the rational numbers.

**What are some unsolved math problems?**

– γ := lim n → ∞ ∑ k = 1 n 1 k − ln n – π + e – π − e (at least one of them must be irrational) – π e – π e (again, at least one of these two must be irrational) – π e – π π – ln π – e e

#### What are some of the oldest unsolved problems in mathematics?

evilquaker asks: “After finding a reference to the (still open) odd perfect number problem, which is claimed to date back to Euclid, I wondered: what are the oldest unsolved math problems? The folklore answer is that the odd perfect number problem is the only one posed by the Greeks which is still open.
