What are the seven wonders of maths?

Answer 1

One should be this:e^(pi * sqrt(-1)) = -1Square root of (-1) is an imaginary number, but in this case, the result isn't! Try to solve it.

Answer 2

The seven wonders of math, also known as the Millennium Prize Problems, are seven unsolved mathematical problems that were identified by the Clay Mathematics Institute in 2000. These problems include the Birch and Swinnerton-Dyer conjecture, the Hodge conjecture, the Navier-Stokes existence and smoothness problem, the P versus NP problem, the Riemann hypothesis, the Yang-Mills existence and mass gap, and the Poincaré conjecture. Solving any of these problems is considered a major achievement in the field of mathematics.
