What is ten divided by two?

ANSWER IS C. FORMULA: COLUMN 3 = COLUMN 2 + COLUMN 1, but anything duplicated between the two images disappears. 1. Row 1: Column 2 is a blue circle with a purple dot in it. Column 1 is just a blue circle. Add C2 to C1 by mentally overlaying the two images. Anything that is duplicated from both images disappears, leaving just the purple dot. Row 2: C2 is a triangle & C1 is a heptagon. Mentally superimpose the two and you can see nothing is duplicated, so the answer is a combination of the two images. Row 3: C2 + C1 = C3 Mentally superimpose C2 over C1 and discard the duplicated parts (blue ring) Note: Because you superimposed C2 over C1, the color from C2 (purple) takes precedence.

For me each row has its own technique.

Row one is: column 2= column 3 + column 1

Row two is: column 1+ column 2= column 3

And finally Row 3 is the observation of what happens in row 2. We notice that something purple plus something blue and white = column two.

So the same thing must happen for row three: So column 2= column3 + column 1 and the only thing that would be perfect for column 3 would be c.

col3 = col2 - col1,

subtraction only works if the shape is 100% identical, else they will overlap

The subtraction won’t work for second row. The totality of shapes= triangle minus polygons would be some weird thing. So that won’t work.

The blue square and the purple square are what's common in rows 1 and 2.
