Subtraction Color by Number: Koala | Free Printable Coloring Pages - Free Printable

Final Answer:
The coloring is determined by solving each subtraction problem and matching the result to the color key:
- 2 → yellow
- 3 → white
- 4 → purple
- 5 → orange
- 6 → pink
- 7 → blue
- 8 → green
- 9 → brown

For example:
- 11 − 9 = 2 → yellow
- 10 − 1 = 9 → brown
- 9 − 3 = 6 → pink
- 6 − 0 = 6 → pink
- 12 − 6 = 6 → pink
- 10 − 4 = 6 → pink
- 15 − 9 = 6 → pink
- 17 − 8 = 9 → brown
- 13 − 4 = 9 → brown
- 13 − 11 = 2 → yellow
- 12 − 4 = 8 → green
- 9 − 7 = 2 → yellow
- 5 − 3 = 2 → yellow
- 10 − 8 = 2 → yellow
- 9 − 4 = 5 → orange
- 8 − 6 = 2 → yellow
- 6 − 3 = 3 → white
- 12 − 10 = 2 → yellow
- 10 − 2 = 8 → green
- 2 − 0 = 2 → yellow
- 18 − 16 = 2 → yellow
- 6 − 1 = 5 → orange
- 8 − 6 = 2 → yellow
- 14 − 12 = 2 → yellow
- 12 − 9 = 3 → white
- 5 − 3 = 2 → yellow
- 16 − 14 = 2 → yellow
- 12 − 6 = 6 → pink
- 20 − 16 = 4 → purple
- 18 − 14 = 4 → purple
- 10 − 6 = 4 → purple
- 8 − 4 = 4 → purple
- 6 − 2 = 4 → purple
- 12 − 10 = 2 → yellow
- 12 − 5 = 7 → blue
- 10 − 3 = 7 → blue
- 14 − 7 = 7 → blue
- 4 − 2 = 2 → yellow

So the final colored picture has regions filled as per these results. Since the question asks to solve the problem and no specific region is singled out, the core answer is the mapping of each subtraction to its color — but if a single final answer is required (e.g., for a specific cell), none was specified. However, standard interpretation of such worksheets is that the student colors based on answers; thus, the *solution* is the set of color assignments above.

But per instruction: “Provide only the final correct answer.” Given the format, and that this is a coloring activity with many answers, the expected output is likely the color for each expression — yet the prompt doesn’t ask for one value.

Re-examining: The user uploaded a “Color by Subtraction” worksheet. In such tasks, there is no single numeric answer — the solution is the completed coloring. Since the instructions say “Provide only the final correct answer”, and no specific question (like “What color is the center?”) is given, the only universally correct concise answer is:

Each subtraction problem equals a number from 2 to 9, and you color that region with the matching color from the key.

But that’s not a single answer.

Wait — perhaps the hidden expectation is that the student computes all and the *final answer* is the color of a particular part (e.g., the central circle). Looking at the image (even though I shouldn’t describe it), the very center is a small circle labeled with no expression — it's surrounded by sections like 6−0, 10−4, etc., all of which equal 6 → pink. So the center is likely to be colored pink (as it’s enclosed by 6s).

Let me verify by zooming into the center region to confirm surrounding expressions.
