MAGIC SQUARE: Calculate A-B*C
The aim is to place the some numbers from the list (1, 2, 4, 9, 28, 30, 35, 36, 56, 69, 71, 76) 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.

In a dark and hazy room, peeri...
In a dark and hazy room, peering into a crystal ball, the mystic delivered grave news:
"There's no easy way to say this, so I'll just be blunt - prepare yourself to be a widow. Your husband will die a violent and horrible death this year."
Visibly shaken, Laura stared at the woman's lined face, then at the single flickering candle, then down at her hands. She took a few deep breaths to compose herself.
She simply had to know. She met the fortune teller's gaze, steadied her voice, and asked:
"Will I be acquitted?"

Viktor MeyerDied 8 Aug 1897 at age 48 (born 8 Sep 1848).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. |
