MAGIC SQUARE: Calculate A-B-C
The aim is to place the some numbers from the list (5, 9, 10, 16, 20, 21, 22, 26, 27, 40) 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 Nasrin 24 T.

Begin by standing on a comfort...
Begin by standing on a comfortable surface, where you have plenty of room at each side. With a 5-lb potato sack in each hand, extend your arms straight out from your sides and hold them there as long as you can. Try to reach a full minute, and then relax. Each day you'll find that you can hold this position for just a bit longer.
After a couple of weeks, move up to 10-lb potato sacks. Then try 50-lbpotato sacks and then eventually try to get to where you can lift a 100-lbpotato sack in each hand and hold your arms straight for more than a full minute. (I'm at this level.)
After you feel confident at that level, put a potato in each of the sacks.

John Adolphus Bernard DahlgrenBorn 13 Nov 1809; died 12 Jul 1870 at age 60. American inventor of the smooth-bore cannon that was, from its shape, familiarly known as the “soda-water bottle.” The shape resulted from a design in which the thickness of metal was varied to match the differences in internal pressure occurring when the cannon was fired. The pressures were determined by boring holes in the walls of the gun and inserting as gauges such objects as pistons or musket balls. He developed the weapons primarily for use on small boats that patrolled the waterways. His iron smoothbores were adopted in 1850 (9-inch gun) and 1851 (11-inch gun). Although designed for use against wooden ships, the iron-clad Monitor class ships carried two of these guns in their turrets, which were replaced by the 15-inch Dahlgrens in 1862. |
