MAGIC SQUARE: Calculate A*B+C
The aim is to place the some numbers from the list (15, 22, 23, 25, 29, 32, 33, 37, 38, 39, 60, 61, 67) 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 Djordje Timotijevic.

Johann Daniel TitiusDied 16 Dec 1796 at age 67 (born 2 Jan 1729).Prussian astronomer, physicist, and biologist whose formula (1766) expressing the distances between the planets and the Sun was confirmed by J.E. Bode in 1772, when it was called Bode's Law. Titius suggested that the mean distances of the planets from the sun very nearly fit a simple relationship of A=4+(3x2n) giving the series 4, 7, 10, 16, 28*, 52, 100, corresponding to the relative distance of the six known planets, up to Saturn, and an unassigned value (*) between Mars and Jupiter. Olbers searched for a planetary object at this empty position, thus discovering the asteroid belt. However, since the discovery of Neptune, which did not fit the pattern, the "law" is regarded as a coincidence with no scientific significance.[DSB gives date of death 16 Dec 1796. EB gives 11 Dec 1796.] |
