Is this a magic square:
08 24 01 06 17
14 05 16 07 23
15 11 22 13 04
21 12 03 19 10
02 18 09 20 25
??????
This is not a magic square as:
Row 1: 08+24+01+06+17=56
Row 2: 14+05+16+07+23=65
Row 3: 15+11+22+13+04=65
Row 4: 21+12+03+19+10=65
Row 5: 02+18+09+20+25=74
And that's without taking the colums and diagonals into consideration!
For magic squares all the rows and all the columns and the 2 diagonals have to add up to the same thing.
You can use a calculator and check if this is the case.
