Can you figure out which signs go in the circles? This math game helps kids practice their addition and subtraction skills.

Let’s solve each equation step by step. We need to fill in the circles with either “+” or “–” so that the left side equals the right side.

Equation 1: 4 ○ 0 ○ 4 = 8

Try:
4 + 0 + 4 = 8 → ✔ Works!
So: + , +

---

Equation 2: 7 ○ 9 ○ 1 = 15

Try:
7 + 9 – 1 = 15? → 16 – 1 = 15 → ✔
Or 7 – 9 + 1 = -1 → no
7 + 9 + 1 = 17 → too big
So: + , –

Wait — let’s check again:
7 + 9 = 16, then 16 – 1 = 15 → yes.
So: + , –

But wait — what if we try 7 – 9 + 1? That’s -1 → no.
What about 7 + 9 + 1? 17 → no.
Only 7 + 9 – 1 works.

Actually — hold on! Let me double-check all possibilities for this one:

Option A: 7 + 9 + 1 = 17
Option B: 7 + 9 – 1 = 15 ✔
Option C: 7 – 9 + 1 = -1 ✘
Option D: 7 – 9 – 1 = -3 ✘

So only +, – works.

BUT — wait a second! The problem might allow different combinations. Let me check if there’s another way.

Nope — only one combination gives 15.

So: + , –

Wait — actually, let me re-read the equation: 7 ○ 9 ○ 1 = 15

Another thought: What if it’s 7 – 9 + 1? No, that’s -1.

Hmm… maybe I made a mistake earlier?

Wait — 7 + 9 is 16, minus 1 is 15 — correct.

So first two are:
Eq1: + , +
Eq2: + , –

Equation 3: 3 ○ 6 ○ 2 = 7

Try:
3 + 6 – 2 = 7 → 9 – 2 = 7 → ✔
3 – 6 + 2 = -1 → no
3 + 6 + 2 = 11 → no
3 – 6 – 2 = -5 → no
So: + , –

---

Equation 4: 8 ○ 6 ○ 7 = 21

Try:
8 + 6 + 7 = 21 → 14 + 7 = 21 → ✔
8 + 6 – 7 = 7 → no
8 – 6 + 7 = 9 → no
8 – 6 – 7 = -5 → no
So: + , +

---

Equation 5: 7 ○ 2 ○ 8 = 1

Try:
7 – 2 – 8 = -3 → no
7 + 2 – 8 = 1 → 9 – 8 = 1 → ✔
7 – 2 + 8 = 13 → no
7 + 2 + 8 = 17 → no
So: + , –

Wait — 7 + 2 = 9, 9 – 8 = 1 → yes.

So: + , –

---

Equation 6: 2 ○ 1 ○ 9 = 10

Try:
2 + 1 + 9 = 12 → no
2 + 1 – 9 = -6 → no
2 – 1 + 9 = 10 → 1 + 9 = 10 → ✔
2 – 1 – 9 = -8 → no
So: – , +

Check: 2 – 1 = 1, 1 + 9 = 10 → perfect.

---

Now let’s list all answers in order:

1. 4 + 0 + 4 = 8 → + , +
2. 7 + 9 – 1 = 15 → + , –
3. 3 + 6 – 2 = 7 → + , –
4. 8 + 6 + 7 = 21 → + , +
5. 7 + 2 – 8 = 1 → + , –
6. 2 – 1 + 9 = 10 → – , +

Wait — let me verify Equation 2 again because 7 + 9 – 1 = 15 is correct, but let me see if there's any trick.

Is there any other combination? For example, could it be 7 – 9 + 1? No, that’s -1.

What about multiplication? But the game only shows + and – buttons at the top, so we can only use those.

Same for all equations — only + and – allowed.

So our solutions are solid.

Final Answer:

For each row, the operators (in order) are:

Row 1: + , +
Row 2: + , –
Row 3: + , –
Row 4: + , +
Row 5: + , –
Row 6: – , +

We can write them as a sequence per row.

Since the question doesn’t specify output format, but from context, likely we list the operator pairs for each equation.

But looking back at the user request — they just want the final answer solved accurately.

Probably best to present each completed equation.

Alternatively, since it’s a grid, maybe list the symbols for each circle.

There are 6 equations, each with 2 blanks → total 12 blanks.

But perhaps simplest is to write each full equation with correct signs.

Let me do that.

Final Answer:
4 + 0 + 4 = 8
7 + 9 – 1 = 15
3 + 6 – 2 = 7
8 + 6 + 7 = 21
7 + 2 – 8 = 1
2 – 1 + 9 = 10
