MAGIC SQUARE: Calculate A*B+C
The aim is to place the some numbers from the list (10, 12, 15, 16, 17, 18, 19, 21, 22, 56, 88) 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 photographer for a national magazine was assigned to get photos of an enormous forest fire. Smoke at the scene was too thick to get any good shots, so he frantically called his home office to hire a plane.
"It will be waiting for you at the airport!" he was assured by his editor.
As soon as he got to the small, rural airport, sure enough, a plane was warming up near the runway. He jumped in with his equipment and yelled, "Let's go! Let's go!" The pilot swung the plane into the wind and soon they were in the air.
"Fly over the north side of the fire," said the photographer, "and make three or four low level passes."
"Why?" asked the pilot.
"Because I'm going to take pictures! I'm a photographer, and photographers take pictures!" said the photographer with great exasperation and impatience.
After a long pause the pilot said, "You mean you're not the instructor?"
"It will be waiting for you at the airport!" he was assured by his editor.

What a winning combination?
The computer chose a secret code (sequence of 4 digits from 1 to 6). Your goal is to find that code. Black circles indicate the number of hits on the right spot. White circles indicate the number of hits on the wrong spot.

Leopold KroneckerDied 29 Dec 1891 at age 68 (born 7 Dec 1823). German mathematician whoworkedwho worked to unify arithmetic, algebra and analysis, with a particular interest in elliptic functions, algebraic equations, theory of numbers, theory of determinants and theory of simple and multiple integrals. However the topics he studied were restricted by the fact that he believed in the reduction of all mathematics to arguments involving only the integers and a finite number of steps. He believed that mathematics should deal only with finite numbers and with a finite number of operations. He was the first to doubt the significance of non-constructive existence proofs, and believed that transcendental numbers did not exist. The Kronecker delta function is named in his honour.« |
