MAGIC SQUARE: Calculate A+B+C
The aim is to place the some numbers from the list (20, 21, 22, 23, 27, 29, 48, 49, 55, 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.

Sir William Rowan HamiltonDied 2 Sep 1865 at age 60 (born 4 Aug 1805). Irish mathematician in the fields of optics, geometrics, and classical mechanics. By age 12, Hamilton had already learned fourteen languages when he met the American, Zerah Colburn, who could perform amazing mental arithmetical feats, and they joined in competitions. It appears that losing to Colburn sparked Hamilton's interest in mathematics. At 15, he began studied the works of LaPlace and Newton so by age 17 had become the greatest living mathematician. He contributed to the development of optics, dynamics, and algebra. His invention of the calculus of quaternions enabled a three-dimensional algebra or geometry which provided a basis for the later development of quantum mechanics. |
