Any answer that you can logically (not necessarily mathematically) justify should be fine. But I'd try working up and down the columns. If you can find a pattern in the first two columns, figure out what the same process would give you in the third column. :wink:

I still don't get it, but i predict that the number in the second matrix square is maybe "1" ? and the number in the first square is unknown to me! ^^ :D

This matrix square can be solved as :
In first square : Multiply the two numbers in the same column : 2 * 6 = 18 (?)
In the second square : Divide the numbers in the same column : 2/1 = 2 (?')

Thank to my stupidness! :D
