Just played a Mensa IQ test online (http://test.mensa.no/)

Answers to these two questions elude me.

Could anyone find out the logic of them? I was puzzled & curious for few days.

First one:

Square + square gives opposite square.
Same for dots - only dot+dot gives opposite dot, otherwise nothing. You could also say it is multiplication for 1 and reverse solution.
So correct answer is D

Second one:

Look at diagonals: 1x3, 2x2, 3x1
1x1, 2x3, 3x2
and 1x2, 2x1, 3x3 = ?
Only one that could fit is E, since there is always only one change. Like one change from 1x3 to 2x2, one change to 3x1 and so on.

With this logic (which seems is the right answer) the picture at the 'down left corner' should not have square on the 'up right side'.
