Answers
Answer:
Divide the sum (90) by the number of figures (9), you find 10.
the center line of the square will be a row of three numbers with 10 in the middle, i.e. 9 10 11. Its sum is three times 10 (because 9 + 11 = 2 * 10).
That is all. Pick any calendar month whereby 10 is not on a side, and select the square of numbers where 10 in in the center place. Example: October 2018, where 10 is a Wednesday. The square will be Tu We Th on three consecutive lines with 10 in the middle.
