<h3>How to solve the puzzle</h3>
To solve this the values at the top of the star were gotten by the addition of two values inside the stars.
- 3 + 12 = 15
- 12 + 4 = 16
- 4 + 2 = 6
- 2 + 10 = 12
- 10 + 3 = 13
Therefore the answer to this question is 13.
Another way of getting the value is by adding 15 + 16 = 31
12 + 6 = 18
31-18 = 13
