What is the rule for magic squares?
Like most of my favorite math games and activities, the rules can be summed up in a sentence or two. Take a 3×3 box like the one at right and fill it with the digits 1-9, using each digit only once. The Magic Square is complete when all rows, all columns, and both diagonals add up to the same number. That’s it!
Can we form a magic square out of the first 9 prime numbers?
A smallest order-3 consecutive primes magic square could be constructed with the nine prime series starting with 99 67943 20667 01086 48449 06536 95853 56163 89823 64080 99161 83957 74048 58552 90714 75461 11479 96776 94651. This series also has a difference of 210 between successive primes.
Is it possible to place the numbers 1 2 3 9 one on each square of a 3 by 3 grid so that the diagonals as well as all the rows and columns add up to prime numbers?
Show that it is impossible to place the numbers 1, 2, 3,…, 9 one on each square of a 3 by 3 grid so that the diagonals, as well as all the rows and columns, add up to prime numbers….Age 7 to 16. Challenge Level.

Are there infinitely many Magic Squares?
Now the infinite square (∞) is indeed an infinite magic square as the series in every row, column and diagonal are equal (in above sense) to the magic constant M = 0. n0 = 1 + ζ(0) + ζ(0) = 0. Thus, it is also an infinite magic square.
How do you find the sum of a magic square?
The sum of a Magic Square is given by the formula The strategy is to fill squares with consecutive numbers by imagining that from your current position on the magic square, you are moving North East. As an example, let’s construct the Lo Shu Square using the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9. Step 1.
What are magic squares?
Magic Squares are square grids with a special arrangement of numbers in them. These numbers are special because every row, column and diagonal adds up to the same number. So for the example below, 15 is the magic number.
How do you construct a magic square of order 8?
The method we use to construct a magic square of order 8 is the same as the method used for the 4 x 4. The only extra consideration is to include leading diagonals of each 4 x 4 ‘sub-square’. Let’s use the numbers 1, 2, 3, 4, …., 64, which give a magic sum of 260.
How do you know if a magic square is bimagic?
If raising each number to the n th power yields another magic square, the result is a bimagic (n = 2), a trimagic (n = 3), or, in general, a multimagic square . A magic square in which the number of letters in the name of each number in the square generates another magic square is called an alphamagic square .
