To solve this puzzle, we need to find the missing number on each star. The rule is:
The sum of all 5 points on a star must equal the number in the center of that star.
Here is the step-by-step calculation for each star with a missing point:
1. Top Left Star (Center: 31)
* Given points: 9, 8, 4
* Sum of given points: $9 + 8 + 4 = 21$
* Missing point: $31 - 21 = \mathbf{10}$
2. Top Middle Star (Center: 34)
* Given points: 9, 8, 8
* Sum of given points: $9 + 8 + 8 = 25$
* Missing point: $34 - 25 = \mathbf{9}$
3. Top Right Star (Center: 25)
* Given points: 8, 2, 4
* Sum of given points: $8 + 2 + 4 = 14$
* Missing point: $25 - 14 = \mathbf{11}$
4. Middle Left Star (Center: 28)
* Given points: 7, 6, 5
* Sum of given points: $7 + 6 + 5 = 18$
* Missing point: $28 - 18 = \mathbf{10}$
5. Center Star (Center: 36)
* Given points: 8, 9, 7
* Sum of given points: $8 + 9 + 7 = 24$
* Missing point: $36 - 24 = \mathbf{12}$
6. Middle Right Star (Center: 29)
* Given points: 9, 6, 1
* Sum of given points: $9 + 6 + 1 = 16$
* Missing point: $29 - 16 = \mathbf{13}$
7. Lower Middle-Left Star (Center: 32)
* Given points: 7, 8, 6
* Sum of given points: $7 + 8 + 6 = 21$
* Missing point: $32 - 21 = \mathbf{11}$
8. Lower Middle-Right Star (Center: 28)
* Given points: 8, 2, 9
* Sum of given points: $8 + 2 + 9 = 19$
* Missing point: $28 - 19 = \mathbf{9}$
9. Far Right Star (Center: 38)
* Given points: 8, 8, 7
* Sum of given points: $8 + 8 + 7 = 23$
* Missing point: $38 - 23 = \mathbf{15}$
10. Bottom Left Star (Center: 31)
* Given points: 1, 8, 8
* Sum of given points: $1 + 8 + 8 = 17$
* Missing point: $31 - 17 = \mathbf{14}$
11. Bottom Middle-Left Star (Center: 38)
* Given points: 8, 8, 3
* Sum of given points: $8 + 8 + 3 = 19$
* Missing point: $38 - 19 = \mathbf{19}$
12. Bottom Middle-Right Star (Center: 33)
* Given points: 7, 3, 8
* Sum of given points: $7 + 3 + 8 = 18$
* Missing point: $33 - 18 = \mathbf{15}$
13. Bottom Right Star (Center: 25)
* Given points: 5, 3, 8
* Sum of given points: $5 + 3 + 8 = 16$
* Missing point: $25 - 16 = \mathbf{9}$
14. Very Bottom Left Star (Center: 30)
* Given points: 1, 9, 9
* Sum of given points: $1 + 9 + 9 = 19$
* Missing point: $30 - 19 = \mathbf{11}$
15. Very Bottom Middle Star (Center: 27)
* Given points: 7, 4, 8
* Sum of given points: $7 + 4 + 8 = 19$
* Missing point: $27 - 19 = \mathbf{8}$
16. Very Bottom Right Star (Center: 28)
* Given points: 6, 3, 8
* Sum of given points: $6 + 3 + 8 = 17$
* Missing point: $28 - 17 = \mathbf{11}$
Final Answer:
The missing star points are:
- Top Row:
10, 9, 11
- Second Row:
10, 12, 13
- Third Row:
11, 9, 15
- Fourth Row:
14, 19, 15, 9
- Bottom Row:
11, 8, 11
