MAGIC SQUARE: Calculate A-B+C
The aim is to place the some numbers from the list (2, 3, 5, 6, 11, 14, 36, 65, 66, 70, 74, 78) 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 passengers were leaving the plane after landing, and one smiling, satisfied passenger paused to congratulate the flight attendant.
"Stewardess," he said happily, "I want to compliment you and the crew and especially the captain for getting here right on time. It's not often that an airline gets to where it's going exactly when they claim it will. I'm going to call your home office and let them know how pleased I am."
"Why, thank you, sir," the flight attendant answered, "but I think you should know something ... this is yesterday's flight."

Caspar WesselDied 25 Mar 1818 at age 72 (born 8 Jun 1745).Norwegian surveyor and mathematician who demonstrated innovative mathematical skills as a surveyor, mathematically processing the triangulation data and preparing maps. From 1764, he worked for the Royal Danish Academy, which was making a topographical survey of Denmark. In his life career, Caspar advanced his knowledge of algebra, trigonometry and mathematical geometry. On 10 Mar 1797, he presented his only mathematical paper to the Academy, containing the first geometric representation of complex numbers, but it wasn't seen internationally. Jean-Robert Argand, found the method independently, and his publication (1806) was circulated, hence the method is known as an Argand diagram. A complex numbers is shown as a point in a Cartesian plane, with the real portion of the number on the x axis and the imaginary part on the y axis.«[Image: An Argand diagram, known by that name, but priority goes to Wessel.] |
