MAGIC SQUARE: Calculate A-B*C
The aim is to place the some numbers from the list (10, 11, 13, 23, 24, 26, 29, 30, 32, 64, 95) 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.

Wife's love
Bill pulled up a stool at his favorite bar and announced: "My wife Suzie must love me more than any woman has ever loved any man!"
"What makes you say that?" the bartender inquired.
"Last week," Bill explained, "I had to take a couple of sick days from work. Suzie was so thrilled to have me around that every time the milkman and the post office guy came by, she'd run down the driveway, waving her arms and hollering, 'My husband's home! My husband's home!'"

Klaus Friedrich RothBorn 29 Oct 1925.German-born British mathematician who was awarded the Fields Medal in 1958. His major work has been in number theory, particularly the analytic theory of numbers. He solved in the famous Thue-Siegel problem (1955) concerning the approximation to algebraic numbers by rational numbers (for which he won the medal). Roth also proved in 1952 that a sequence with no three numbers in arithmetic progression has zero density (a conjecture of Erdös and Turán of 1935). |
