Halloween addition math activity for kids featuring a Frankenstein monster.

Okay, now I'm looking at the central lower part of the Frankenstein monster, which includes the collar and the top of the body. I can clearly read several math problems here: "8 + 2", "1 + 2", "2 + 7", "2 + 9", "7 + 2", "3 + 2", "2 + 0", and another "7 + 2". I will solve these one by one. First, 8 + 2 equals 10, which is green. Next, 1 + 2 equals 3, which is orange. Then, 2 + 7 equals 9, which corresponds to black. Following that, 2 + 9 equals 11, which is gray. Then, 7 + 2 equals 9, so that's also black. After that, 3 + 2 equals 5, which is purple. Next, 2 + 0 equals 2, which is white. Finally, the last "7 + 2" also equals 9, so that section should be colored black. I have now solved all the math problems in the entire image. I will now compile a complete list of all the solutions and their corresponding colors to provide the final answer.

Based on the analysis of the "Color by Code" addition worksheet, the solution involves solving each addition problem and coloring the corresponding section according to the provided code. Here is a complete list of the problems and their correct colors:

- 2 + 4 = 6 → Light Blue
- 5 + 2 = 7 → Dark Blue
- 2 + 5 = 7 → Dark Blue
- 4 + 2 = 6 → Light Blue
- 8 + 2 = 10 → Green
- 2 + 7 = 9 → Black
- 2 + 10 = 12 → Yellow
- 10 + 2 = 12 → Yellow
- 2 + 1 = 3 → Orange
- 1 + 2 = 3 → Orange
- 3 + 2 = 5 → Purple
- 2 + 3 = 5 → Purple
- 2 + 6 = 8 → Pink
- 6 + 2 = 8 → Pink
- 2 + 9 = 11 → Gray
- 7 + 2 = 9 → Black
- 2 + 0 = 2 → White

By following this guide and coloring each section with its assigned color, the Frankenstein monster will be revealed in its full, colorful glory.
