A man went to his lawyer and told him, "My neighbor owes me $500 and he doesn't want to pay up. What should I do?"
"Do you have any proof?" asked the lawyer.
"Nope," replied the man.
"Okay, then write him a letter asking him for the $1000 he owed you," said the lawyer.
"But it's only $500," replied the man.
"Precisely. That's what he will reply and we will have the proof we need to nail him."
"Do you have any proof?" asked the lawyer.
"Nope," replied the man.

Goldbach's conjectureIn 1742, the Russian mathematician Christian Goldbach dated a letter to Leonhard Euler in which he presented his famous conjecture. Stated in modern terms, Goldberg's conjecture proposes that “Every even natural number greater than 2 is equal to the sum of two prime numbers.”It has been checked by computer for vast numbers - up to at least 4 x 1014 - but still remains unproved. Goldbach also studied infinite sums, the theory of curves and the theory of equations.«[Image: Letter to Euler, in which Goldbach presented his conjecture.] |

MAGIC SQUARE: Calculate A-B+C
The aim is to place the some numbers from the list (7, 8, 15, 19, 20, 25, 26, 27, 33, 81) into the empty squares and squares marked with A, B an C. Sum of each row and column should be equal. All the numbers of the magic square must be different. Find values for A, B, and C. Solution is A-B+C. The first user who solved this task is Nasrin 24 T.
