MAGIC SQUARE: Calculate A*B+C
The aim is to place the some numbers from the list (7, 11, 12, 13, 30, 31, 32, 67, 69, 70, 71, 94) 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.

Johannes Robert RydbergDied 28 Dec 1919 at age 65 (born 8 Nov 1854).Swedish physicist, known for the Rydberg constant in his empirical formula that related the wave numbers of the spectral lines of an element (1890). This formula expressed fundamental relationships in those lines, which he presumed were the result of the inner nature and structure of an element's atoms. In 1897, he suggested that an atomic number for each of the elements, rather than atomic weights, would be a better means for organizing the elements and their periodicity of their characteristics. His work did provided the basis for discovering the electron shell structure of the atom. It was later established that the integer number of positive charges on an element's nucleus (its number of protons) corresponded to his idea of atomic number.« |
