MAGIC SQUARE: Calculate A*B+C
The aim is to place the some numbers from the list (6, 7, 9, 10, 11, 12, 19, 22, 24, 60) 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.
Find number abc
If ac3a7 - cbb1c = c3a4a find number abc. Multiple solutions may exist.
What a winning combination?
The computer chose a secret code (sequence of 4 digits from 1 to 6). Your goal is to find that code. Black circles indicate the number of hits on the right spot. White circles indicate the number of hits on the wrong spot.

Credit Cards
Abe and Esther are flying to Australia for a two week vacation to celebrate their 40th anniversary.
Suddenly, over the public address system, the Captain announces, "Ladies and Gentlemen, I am afraid I have some very bad news. Our engines have ceased functioning and we will attempt an emergency landing.
Luckily, I see an uncharted island below us and we should be able to land on the beach. However, the odds are that we may never be rescued and will have to live on the island for the rest of our lives!"
Thanks to the skill of the flight crew, the plane lands safely on the island. An hour later Abe turns to his wife and asks, "Esther, did we pay our $5,000 PBS pledge check yet?"
No, sweetheart," she responds.
Abe, still shaken from the crash landing, then asks, "Esther, did we pay our American Express card yet?"
"Oh, no! I'm sorry. I forgot to send the check," she says.
"One last thing, Esther. Did you remember to send checks for the Visa and MasterCard this month?" he asks.
"Oh, forgive me, Abie," begged Esther. "I didn't send that one, either."
Abe grabs her and gives her the biggest kiss in 40 years.
Esther pulls away and asks him, "What was that for?"
Abe answers, "They'll find us!"

Ferdinand BraunBorn 6 Jun 1850; died 20 Apr 1918 at age 67.Karl Ferdinand Braun was a German physicist whosharedthe Nobel Prize for Physics in 1909 with Guglielmo Marconi for the development of wireless telegraphy. He published papers on deviations from Ohm's law and on the calculations of the electromotive force of reversible galvanic elements from thermal sources, and discovered (1874) the electrical rectifier effect. He demonstrated the first cathode-ray oscilloscope (Braun tube) in 1897, after work on high-frequency alternating currents. Cathode-ray tubes had previously been characterized by uncontrolled rays; Braun succeeded in producing a narrow stream of electrons, guided by means of alternating voltage, that could trace patterns on a fluorescent screen. |
