Math subtraction puzzles up to 20 - Free Printable

Let’s solve this step by step.

We have a grid of subtraction problems. Each answer will tell us which puzzle piece to pick — because each puzzle piece has a number on it, and that number matches the answer to one of the subtractions.

First, let’s calculate all the answers:

Row 1:
- 1 - 1 = 0
- 7 - 2 = 5
- 15 - 6 = 9
- 9 - 3 = 6

Row 2:
- 14 - 12 = 2
- 4 - 3 = 1
- 8 - 4 = 4
- 17 - 1 = 16

Row 3:
- 6 - 3 = 3
- 20 - 8 = 12
- 10 - 2 = 8
- 19 - 4 = 15

Now we have these answers:
0, 5, 9, 6, 2, 1, 4, 16, 3, 12, 8, 15

These numbers match the labels on the puzzle pieces below. So we need to collect the puzzle pieces labeled with those numbers and put them together to form a picture.

Looking at the puzzle pieces:

- Piece 0 → blank? (maybe background or center)
- Piece 1 → curved line
- Piece 2 → leaf-like shape
- Piece 3 → flower petal part
- Piece 4 → curve
- Piece 5 → circle with stem (like an eye or head)
- Piece 6 → blank? (another empty space?)
- Piece 8 → foot/leg shape
- Piece 9 → another circle with stem (other side?)
- Piece 12 → leg/foot shape
- Piece 15 → petal or wing
- Piece 16 → leaf

Wait — actually, looking again, some pieces are meant to fit together to make a character or animal.

Let’s think about what makes sense when assembled.

Pieces 5 and 9 both look like eyes (circles with stems). That suggests they go on top — maybe for a face.

Piece 0 is blank — perhaps the center of the face?

Pieces 1, 4, 6 might be parts of the body or outline.

Pieces 2 and 16 are leaves — maybe wings or ears?

Pieces 3 and 15 look like petals or wings too.

Pieces 8 and 12 are feet — so likely bottom part.

Actually, if you assemble all the pieces with the correct numbers, you get a cute bird or duckling!

But since the question doesn’t ask “what is the picture?” but rather implies we just need to solve the math to know which pieces to use — and we’ve done that — then our job is done once we’ve matched every problem to its answer and thus to its piece.

So the final answer isn’t a single number — it’s the set of puzzle pieces corresponding to the answers we calculated.

But wait — maybe the task expects us to realize that after solving all the subtractions, we can assemble the image. Since no specific output format was given beyond “solve the problem”, and the only thing to “solve” here is matching the math to the pieces…

Actually, re-reading the instructions: “Solve the problem accurately.” The problem is essentially: do the math, then use the answers to select the right puzzle pieces. But since we’re not physically assembling them, perhaps the expected answer is simply listing the answers in order? Or confirming that all pieces are used?

Wait — there are 12 math problems and 12 puzzle pieces shown (numbered 0,1,2,3,4,5,6,8,9,12,15,16) — exactly matching our 12 answers.

So the solution is complete when we’ve computed all 12 differences correctly.

Therefore, the final answer should be the list of answers in the same order as the grid:

Grid row by row:

Row 1: 0, 5, 9, 6
Row 2: 2, 1, 4, 16
Row 3: 3, 12, 8, 15

That’s the full solution.

Final Answer:
0, 5, 9, 6, 2, 1, 4, 16, 3, 12, 8, 15
