MAGIC SQUARE: Calculate A-B+C
The aim is to place the some numbers from the list (6, 8, 15, 19, 21, 26, 28, 61, 63, 70) 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.

I have loved. I have lost and I have changed
I have loved. I have lost and I have changed. It has been difficult but I have learned so much from it. I have learned that people can hurt you so deeply and not even worry about you. I learned that good people can change in a minute when their hearts have been broken. I've met great people, but mean people as well. But the most important thing I have learned is that every person in this world is strong enough to let go . People come and go and that’s life ! The most important thing is to stand up and realize that you deserve something better than a person that gives up on you.
Which is a winning combination of digits?
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.

Richard HammingBorn 11 Feb 1915; died 7 Jan 1998 at age 82. Richard Wesley Hamming was an American computer scientist and mathematician whodevisedcomputer Hamming codes - error-detecting and correcting codes (1947). These add one or more bits to the transmission of blocks of data, used for a parity check, so that errors can be corrected automatically. By making a resend of bad data unnecessary, efficiency improved for modems, compact disks and satellite communications. He also worked on programming languages, numerical analysis and the Hamming spectral window (used to smooth data before Fourier analysis is carried out). He taught at University of Louisville, then during WW II worked (1945) on computers with the Manhattan Project creating the atomic bomb. From 1946, he spent 30 years with Bell Telephone Labs, eventually becoming head of computing science research.« |
