Is 3 because 3 times 3 equals 9
You can add them like this:
so if 156 + 213 + 109 was the equation then you would
first put them in order from biggest to smallest
213
156
+109
-----------
then add:
¹ ← ←
213 ↑
156 ↑
+109 ↑
---------↑ ( carry the 10 )
478 (add the ¹ )
then you get the answer 478!
hope that helps :)
Possible points can be (-3,-7) if moved 8 coordinates to the left, (5,1) if moved 8 coordinates upwards, and (13,-7) if moved 8 coordinates to the right.
