Step-by-step solution for: 30 Thought-Provoking Math Puzzles for Middle Schoolers
It looks like you've uploaded an image containing a math puzzle with two parts:
1. A grid of numbers where certain cells are circled.
2. A list of equations on the left, each with a blank to fill in (e.g., `□ + 8 = 10`).
3. Instructions: "Write operation. Write sign. Circle."
Let’s analyze and solve this step by step.
---
The grid is a 10×10 matrix filled with digits from 0 to 9. Some numbers are circled — specifically, in the second row (counting from top), the number 6 is circled, and it's located at position (2,3) if we count rows and columns starting from 1.
But more importantly, there’s a circle around “6” and “2”, forming “6+2” in the grid.
Wait — looking closely, in the second row, the sequence is:
```
7 6 5 4 3 2 1 0 9 8
```
But actually, let's check the actual layout from your image:
From the image:
- The second row (index 1) is:
`7 6 2 0 6 5 3 8 0 2 0 1 8 2 7` — wait, that can't be right because the grid seems to have 10 columns.
Wait — actually, the grid appears to have 10 columns and 10 rows.
Let me reconstruct the grid properly based on what's visible:
Here’s the grid as given:
```
Row 1: 2 5 7 3 12 10 6 8 7 10
Row 2: 7 6 2 0 6 5 3 8 0 2
Row 3: 6 5 8 9 6 2 8 6 3 0
Row 4: 0 6 7 5 8 6 5 8 0 5
Row 5: 1 0 2 6 5 4 3 8 0 2
Row 6: 0 7 1 2 0 1 2 8 6 7
Row 7: 0 8 6 2 1 0 2 8 6 7
Row 8: 0 7 8 0 0 8 6 5 3 8
Row 9: 0 0 7 8 9 6 5 3 8 0
Row 10: 0 0 7 8 9 6 5 3 8 0
```
Wait — some numbers seem to be double-digit (like 12, 10), but likely those are just single digits misread.
Actually, upon closer inspection, "12" and "10" appear in the first row — so maybe the grid contains numbers up to 12? But that doesn’t make sense for a digit grid.
Alternatively, perhaps "12" is meant to be "1" and "2" in adjacent cells.
Looking carefully:
First row:
`2 5 7 3 12 10 6 8 7 10` → likely typo or formatting issue.
But in the image, it’s probably meant to be individual digits. Let's assume the grid is composed of single digits.
Rechecking:
In the image, the first row is:
`2 5 7 3 1 2 1 0 6 8 7 10` — no, that’s not right.
Wait — perhaps the grid is 10x10, and the numbers are all single digits.
Let me re-express the grid clearly:
From your image, here’s the grid (10 rows, 10 columns):
```
Row 1: 2 5 7 3 1 2 1 0 6 8
Row 2: 7 6 2 0 6 5 3 8 0 2
Row 3: 6 5 8 9 6 2 8 6 3 0
Row 4: 0 6 7 5 8 6 5 8 0 5
Row 5: 1 0 2 6 5 4 3 8 0 2
Row 6: 0 7 1 2 0 1 2 8 6 7
Row 7: 0 8 6 2 1 0 2 8 6 7
Row 8: 0 7 8 0 0 8 6 5 3 8
Row 9: 0 0 7 8 9 6 5 3 8 0
Row 10: 0 0 7 8 9 6 5 3 8 0
```
Now, look at the circled numbers: in row 2, the numbers 6 and 2 are circled together, and they form 6+2=8.
But wait — the circle includes both 6 and 2, which are in row 2, columns 2 and 3.
So:
- Row 2: `[7, 6, 2, 0, 6, 5, 3, 8, 0, 2]`
- So column 2: 6, column 3: 2 → 6 and 2 circled.
And nearby, in the same row, after that, we have 3, 8, etc.
But the instruction says: "Write operation. Write sign. Circle."
Also, there’s a LOOK box with an arrow pointing to the circled area.
So perhaps the idea is to find operations such that the result matches the equation on the left.
---
We have:
```
□ + 8 = 10
□ + 12 = ?
□ + 6 = ?
□ + 1 = ?
□ + 5 = ?
□ + 3 = ?
□ + 4 = ?
□ + 7 = ?
□ + 2 = ?
□ + 7 = ?
```
Wait — the last one is repeated: `□ + 7 = ?` twice.
But actually, the list is:
1. □ + 8 = 10
2. □ + 12 = ?
3. □ + 6 = ?
4. □ + 1 = ?
5. □ + 5 = ?
6. □ + 3 = ?
7. □ + 4 = ?
8. □ + 7 = ?
9. □ + 2 = ?
10. □ + 7 = ?
So 10 equations, but the first one has a known result: □ + 8 = 10 → so □ = 2.
That’s our clue.
So the missing number is 2.
Now, look back at the grid.
We see that in row 2, 6 and 2 are circled. And 6 + 2 = 8.
But also, notice that in the first equation, we have:
> □ + 8 = 10 → so □ = 2
So the answer is 2.
But why is 2 circled in the grid?
Ah! Perhaps the operation is addition, and we’re supposed to find numbers in the grid that add up to something.
But wait — the circled numbers are 6 and 2, and their sum is 8.
But 8 appears in the equation: □ + 8 = 10 → so □ = 2.
So the missing number is 2, which is already in the grid.
But how do we use the grid?
Maybe the idea is: find the number that completes the equation, and it should be found in the grid.
But all the equations are of the form: □ + X = Y, but only the first one has Y given.
Wait — no, only the first one has the full equation with result.
All others have blanks on the right.
Wait — actually, looking again:
```
□ + 8 = 10
□ + 12 = □
□ + 6 = □
...
```
Oh! Wait — the right-hand side is also blank in most cases.
So we need to fill in the blanks.
But the only complete equation is the first one:
> □ + 8 = 10 → so □ = 2
So the missing number is 2.
Now, the task might be: use the grid to verify or find the missing number.
But we already know it's 2.
Now, the circle in the grid highlights 6 and 2 — perhaps indicating that 6 + 2 = 8, and 8 is used in the first equation.
So maybe the operation is addition, and the sign is +.
And we are to write the operation and write the sign.
Also, circle the numbers involved.
But the instructions say: "Write operation. Write sign. Circle."
So likely:
- Operation: Addition
- Sign: +
- Circle: the numbers involved — like 6 and 2
But why are they circled?
Because 6 + 2 = 8, and 8 is used in the equation: □ + 8 = 10 → so □ = 2.
So the number 2 is both in the circle and the answer.
Alternatively, maybe the puzzle is to solve the equations using the grid.
But most equations have unknown results.
Unless the results are to be found in the grid.
But that seems unlikely.
Another possibility: the grid contains the answers, and we need to find them.
But the only equation with a known result is the first one.
Let’s try solving the first one:
> □ + 8 = 10 → □ = 2
So the missing number is 2.
Now, 2 appears many times in the grid.
But the circle is around 6 and 2, which are adjacent.
And 6 + 2 = 8, which is the number in the equation.
So perhaps the idea is:
- The operation is addition
- The sign is +
- The circle indicates 6 + 2 = 8
- Then, using that, we solve: □ + 8 = 10 → □ = 2
So the answer is 2
And we are to write the operation: addition, write the sign: +, and circle the numbers involved.
But the circle is already drawn around 6 and 2.
So perhaps the task is to recognize that the operation is addition, and use it to solve the equations.
But only the first one has a complete equation.
Wait — maybe the equations are not all independent — perhaps they are clues to find numbers in the grid.
But without more info, let’s go back.
Alternative idea: the circled numbers are part of a hidden message or code.
But we have:
- Circled: 6 and 2
- Their sum: 8
- In the first equation: □ + 8 = 10 → □ = 2
So the answer is 2
And since 2 is circled, that’s the key.
Moreover, the arrow in the LOOK box points to the circle, emphasizing it.
So likely, the solution is to realize that 6 + 2 = 8, and then use that to solve □ + 8 = 10 → □ = 2.
Thus, the missing number is 2.
Now, the instructions say:
> Write operation. Write sign. Circle.
So:
- Operation: Addition
- Sign: +
- Circle: the numbers involved (6 and 2)
But the circle is already there.
So perhaps the student is to write "addition" and "+", and recognize the circled numbers.
But the problem is asking us to solve it.
---
The circled numbers are 6 and 2, and their sum is 8.
This relates to the first equation:
> □ + 8 = 10
Solving:
> □ = 10 - 8 = 2
So the missing number is 2.
Therefore:
- Operation: Addition
- Sign: +
- Answer: 2
And the circle emphasizes the numbers 6 and 2 that sum to 8, which is used in the equation.
---
- Operation: Addition
- Sign: +
- Missing number: 2
The circled numbers 6 and 2 are added to get 8, which is used in the equation □ + 8 = 10, leading to □ = 2.
Thus, the solution is 2.
1. A grid of numbers where certain cells are circled.
2. A list of equations on the left, each with a blank to fill in (e.g., `□ + 8 = 10`).
3. Instructions: "Write operation. Write sign. Circle."
Let’s analyze and solve this step by step.

Row 9: 0 0 7 8 9 6 5 3 8 0

Now, look at the circled numbers: in row 2, the numbers 6 and 2 are circled together, and they form 6+2=8.
But wait — the circle includes both 6 and 2, which are in row 2, columns 2 and 3.
So:

But the instruction says: "Write operation. Write sign. Circle."
Also, there’s a LOOK box with an arrow pointing to the circled area.
So perhaps the idea is to find operations such that the result matches the equation on the left.

Step 2: Look at the Equations on the Left
We have:
```
□ + 8 = 10
□ + 12 = ?
□ + 6 = ?
□ + 1 = ?
□ + 5 = ?
□ + 3 = ?
□ + 4 = ?
□ + 7 = ?
□ + 2 = ?
□ + 7 = ?
```
Wait — the last one is repeated: `□ + 7 = ?` twice.
But actually, the list is:
1. □ + 8 = 10
2. □ + 12 = ?
3. □ + 6 = ?
4. □ + 1 = ?
5. □ + 5 = ?
6. □ + 3 = ?
7. □ + 4 = ?
8. □ + 7 = ?
9. □ + 2 = ?
10. □ + 7 = ?
So 10 equations, but the first one has a known result: □ + 8 = 10 → so □ = 2.
That’s our clue.
So the missing number is 2.
Now, look back at the grid.
We see that in row 2, 6 and 2 are circled. And 6 + 2 = 8.

Final Answer:
The circled numbers are 6 and 2, and their sum is 8.
This relates to the first equation:
> □ + 8 = 10
Solving:
> □ = 10 - 8 = 2
So the missing number is 2.
Therefore:
- Operation: Addition
- Sign: +
- Answer: 2
And the circle emphasizes the numbers 6 and 2 that sum to 8, which is used in the equation.
---
✔ Solution:
- Operation: Addition
- Sign: +
- Missing number: 2
The circled numbers 6 and 2 are added to get 8, which is used in the equation □ + 8 = 10, leading to □ = 2.
Thus, the solution is 2.
