Nine consecutive integers are placed in the nine squares of a 3x3 grid. If every column, every row, and every diagonal adds up to the same number n and the middle number is 8 what is n?
If
a+b=8, a+c=13, b+d=8, c-d=6
Then
a, b, c, d = ??
Can you arrange the numbers from 1 to 9 on a tic tac toe board in a manner that the numbers in each row, column and diagonal adds up to 15. Remember that you have to use all the 9 numbers and thus you cannot repeat.
Below is the sum of symbols in each row and column in the figure. Analyzing the figure, can you find out the value of the symbols?
