Grandfather Outsmarts Scammers Solving Riemann Hypothesis

Vasily Semerenko is an old man. He is seventy-two years old and lives in Russia. He solved a hard math problem because of some bad people.

The bad people called him on the phone. They wanted him to prove something for money. They told him his grandson had problems, but it was a lie.

At first, he tried a different problem. But he could not finish it well. Then he tried the Riemann hypothesis and found a solution.

He sent his proof to a math place in America. They checked it and said it was right. But they could not give him the money because of rules against Russia.

The man remembered he did not have a grandson. He knew he was tricked. Someone from America came to talk to him about the problem.
