 Primal Magic Square (Posted on 2004-03-09)
Find a 3x3 magic square that is composed of 9 prime numbers (not the numbers from 1-9) and show how you found it.

(A magic square, as you may already know, is one in which the respective sums of the numbers in all the rows, columns, and both major diagonals all add up to the same number.)

First, I think your interpretation is "literally" correct.  But I didn't mean that one couldn't use the primes: 2, 3, 5, and 7... just that the solver wasn't to use ONLY the 9 numbers (1-9).

That being said, Jane, your solution is a correct one.  Unfortunately, I'm guessing that you found this on the internet or in a book, or some other source, as you did not show how you found it.

For others' benefit, there ARE other solutions to this problem.
