Difficult math problem?
My teacher has a extra credit puzzle that's worth a large sum of points. So the puzzle involves a 5X5 square with 25 slots. Each slo has seemingly random numbers inside, So 5 slots need to be chosen and each slot needs to be in a different row and column of the other selected slots, kind of like sodoku. Somehow if all 5 of these random slots are selected, the numbers inside them will always equal a number when all of them are added. Can anyone tell me the solution to this puzzle, and how you come up with the numbers to equal the designated answer? 10 pts for the most simplified straight forward answer

i think you mean a magic square like the one below, which adds up to 65 for each row, column and the 2 main diagonals

problem a million ? i^2 = (a million/3) n^3 + (a million/2) n^2 + (a million/6) n hence a hundred ? i^2 = a hundred [ (a million/3) (59)^3 + (a million/2) (59)^2 + (a million/6) (59) ] problem 2 ? i^3 = (a million/4) n^4 + (a million/2) n^3 + (a million/4) n^2 hence = 10 ? i^2 (i-40 9) = 10 ? i^3 - 490 ? i^2 = 10 [ (a million/4) (a hundred)^4 + (a million/2) (a hundred)^3 + (a million/4) (a hundred)^2 ] - 10 [ (a million/4) (59)^4 + (a million/2) (59)^3 + (a million/4) (59)^2 ] - 490 [ (a million/3) (a hundred)^3 + (a million/2) (a hundred)^2 + (a million/6) (a hundred) ] + 490 [ (a million/3) (59)^3 + (a million/2) (59)^2 + (a million/6) (59) ]
