you add up the numbers in the left and the upper corner. then you multiply this number with the Number in the right corner. And then you have the number in the middle :)
8+3 =11; 11 * 4=44
7+9=16; 16 * 2=32
7+8=15; 15 * ?=75
you have simply to divide the Number in the middle(75) through the number you get, when you add up the left and the upper corner (15) to get the number in the right corner.
The number in the right corner is 5.
