MAGIC SQUARE: Calculate A*B+C
The aim is to place the some numbers from the list (10, 12, 15, 16, 17, 18, 19, 21, 22, 56, 88) 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.

You've all heard of the Air F...
You've all heard of the Air Force's ultra-high-security, super-secret base in Nevada, known simply as "Area 51"?
Well, late one afternoon, the Air Force folks out at Area 51 were very surprised to see a Cessna landing at their "secret" base. They immediately impounded the aircraft and hauled the pilot into an interrogation room.
The pilot's story was that he took off from Las Vegas, got lost, and spotted the Base just as he was about to run out of fuel. The Air Force started a full FBI background check on the pilot and held him overnight during the investigation.
By the next day, they were finally convinced that the pilot really was lost and wasn't a spy. They gassed up his airplane, gave him a terrifying "you-did-not-see-a-base" briefing, complete with threats of spending the rest of his life in prison, told him Las Vegas was that-a-way on such-and-such a heading, and sent him on his way.
The next day, to the total disbelief of the Air Force, the same Cessna showed up again. Once again, the MP's surrounded the plane ... only this time there were two people in the plane.
The same pilot jumped out and said, "Do anything you want to me, but my wife is in the plane and you have to tell her where I was last night!"

Tay Bridge collapseIn 1879, at about 7:15 pm, as a train crossed the Tay Bridge during a gale, the central navigation spans collapsed. The locomotive and six carriages of pasengers fell into the Firth of Tay at Dundee, killing over 80 people, with no survivors. The Tay bridge, then the longest bridge in the world, had 85 spans and was nearly 2 miles long. The collapse of the bridge, opened only 19 months before, shocked the Victorian engineering profession and general public. The Court of Inquiry concluded that inadequate design and construction led to insufficient cross bracing to withstand the gale force winds. The designer, Sir Thomas Bouch, died only ten months after the disaster. To date, it remains the worst structural engineering failure in the British Isles.«[Image: collapsed span in water beside broken columns after the collapse of the Tay Bridge.] |
