My problem to find the treasure.

Hi today at school we had a challenge to do all of these maths questions and once you found the 1st answer which could be a 4 so I would move 4 squares up,down or side to side and you had to do it like a compass so it would have a question like 4 + __?= 8 and so the answer is (4)? and so I that is my maths and I hope that you liked it
