MAGIC SQUARE: Calculate A*B-C
The aim is to place the some numbers from the list (3, 4, 7, 8, 12, 13, 14, 23, 27, 32, 62) 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.

Viktor MeyerBorn 8 Sep 1848; died 8 Aug 1897 at age 48.German organic chemist who contributed greatly to knowledge of both organic and inorganic chemistry and invented an apparatus for determining vapour densities (and hence molecular weights), now named after him. In 1871, Meyer experimentally proved Avogadro's hypothesis by measuring the vapour densities of volatile substances (molecular weight, or relative molecular mass, is twice the vapour density). He went on to determine the vapour densities of inorganic substances at high temperatures. From benzene obtained from petroleum, Meyer in 1883 isolated thiophene, a heterocyclic compound containing sulphur, which much later was to become an important component of various synthetic drugs. |
