I have a puzzle that I did not know how it could be solved
Which numbers should be filled on the blank spaces ? I only figure out that 4 + 20 = 24 and 1 + 20 = 21 then 8 + 20 = 28 I am not sure please help, thanks !
Observing that along the two "lines" we have from top to bottom we have top + middle = bottom, we might take that to be a general rule. That gives us
9 in bottom left (from right column), then
-11 in top left (from NW-SE diagonal), then
32 in centre left (from left column).
I really don't think there's enough information here to make it unambiguous what whoever created this puzzle has in mind; but that's my best guess.
