Dated Magic Square

How to brand a Dated Magic Square?

1.    In the offset row, write downwardly the appointment for which you lot desire to practise the Magic square.

Remember to carve upwards the twelvemonth into two. I guide keep taken the appointment every 2d 13.11.2011.

 

2.    Write whatsoever 3 consecutive numbers in the boxes every 2d shown below.

 3.    Calculate the magic constant which is the amount of elements of each row, column, diagonal); past times summing upwards the elements of offset row. Magic constant =13+11+20+11 = 55.

4.    Now, calculate the chemical cistron inwards row2, column 3 past times subtracting the other 3 elements of that sub-square by magic constant.

55 – (20+11+6) = 18.

5.    Now, honour the blank box of column 3 past times subtracting the amount of other elements from magic constant. 55-(20+18+4) = 13.

6.    Follow the same agency to consummate the row 2, column 2 chemical cistron from fundamental sub-square. 55-(18+13+5) =19

7.    2^nd row 1^st column volition survive 55 – (19 + xviii + 6) =12

           4^th row 2^nd column volition survive 55 – (11 + xix + 5) = 20

 8.    4^th row 1^st column volition survive 55 – (11 + xviii + 5) = 21

            4^th row 4^th column volition survive 55 – (13 + xix + 13) = 10

9.    3^rd row 1^st column = 55 – (13 + 12 + 21) =9

            3^rd row 4^th column = 55 – (11 + vi + 10) = 28

Observe that when you lot add together the numbers given inwards each row, each column or fifty-fifty diagonally, you lot instruct the same sum.
