Re: Magic square, 5x5, even numbers from 2 to 50 totalling 130
You can of course just halve all the entries to get a more traditional puzzle. Here's a solution to that version. Here's a Wikipedia page discussing the general method; perhaps your son was supposed to use it in this case himself.
Edit: I remembered that I dislike it when mathematicians aren't explicit when they easily could be, so here's an explicit solution:
Code:
34 48 2 16 30
46 10 14 28 32
8 12 26 40 44
20 24 38 42 6
22 36 50 4 18

Thanks, it was an assignment but the teacher did not teach them any method in finding the answer. I am now trying to learn that method in the link you provided, thank you so much!
