placing numbers (Posted on 2007-03-12) Difficulty: 4 of 5
You need to make it so that the sum in every row and column will be equal. To do that, you need to select two positive integers. The only numbers that you can place in the grid are those two integers, their sum, their difference, their product, or their quotient. You can place only whole numbers.







Can you complete the grid?

Even after choosing the two numbers, there'd be 5^30 ways to try choosing the combinations to fit the blank spaces, or about 10^21.  It would take "forever" to run a blind brute force program.
