MAGIC SQUARE: Calculate A-B-C
The aim is to place the some numbers from the list (4, 6, 7, 16, 26, 28, 29, 40, 47, 49, 50) 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.#brainteasers #math #magicsquare

Seth Carlo ChandlerDied 31 Dec 1913 at age 67 (born 17 Sep 1846).Seth Carlo Chandler, Jr. was an American astronomer best known for his discovery (1884-85) of the Chandler Wobble, a complex movement in the Earth's axis of rotation (now refered to as polar motion) that causes latitude to vary with a period of 14 months. His interests were much wider than this single subject, however, and he made substantial contributions to such diverse areas of astronomy as cataloging and monitoring variable stars, the independent discovery of the nova T Coronae, improving the estimate of the constant of aberration, and computing the orbital parameters of minor planets and comets. His publications totaled more than 200. |
