1. (24 □ 9) □ 1 = 217

We need to find two operations such that:

(24 □ 9) □ 1 = 217

Try possible combinations:

- Try multiplication first:
24 × 9 = 216
Then 216 + 1 = 217 ✔

So:
(24 × 9) + 1 = 217

✔ Answer: × and +

2. 32 □ (5 □ 10) = 480

Try possibilities:

First, compute inside parentheses:
- 5 + 10 = 15 → 32 × 15 = 480 ✔

So:
32 × (5 + 10) = 480

✔ Answer: × and +

3. (7 □ 2) □ 13 = 18

Try:
- 7 + 2 = 9 → 9 + 13 = 22 ✘
- 7 × 2 = 14 → 14 + 13 = 27 ✘
- 7 × 2 = 14 → 14 + 13 = 27 ✘
- 7 + 2 = 9 → 9 + 13 = 22 ✘
- 7 × 2 = 14 → 14 + 13 = 27 ✘
Wait — try:
- 7 × 2 = 14 → 14 + 13 = 27 ✘
- 7 + 2 = 9 → 9 + 13 = 22 ✘

Wait — maybe:
Try: (7 × 2) = 14, then 14 + 13 = 27 ✘

Try: (7 + 2) = 9, 9 + 13 = 22 ✘

Try: (7 × 2) = 14, 14 + 13 = 27 ✘

Wait — what if it's:
(7 + 2) = 9 → 9 × 2 = 18? But we have 13, not 2.

Wait — try:
(7 × 2) = 14 → 14 + 13 = 27 ✘

Try: (7 + 2) = 9 → 9 + 13 = 22 ✘

Wait — what if:
(7 × 2) = 14 → 14 + 13 = 27 ✘

Hmm.

Try: (7 + 2) = 9 → 9 × 2 = 18, but we have 13.

Wait — maybe:
(7 × 2) = 14 → 14 + 13 = 27 ✘

Wait — perhaps:
(7 + 2) = 9 → 9 × 2 = 18 → but second operand is 13.

Wait — maybe subtraction?

Try: (7 + 2) = 9 → 9 × 2 = 18 → no.

Wait — try:
(7 × 2) = 14 → 14 + 13 = 27 ✘

Wait — try:
(7 + 2) = 9 → 9 + 13 = 22 ✘

Wait — maybe:
(7 × 2) = 14 → 14 + 13 = 27 ✘

Wait — let's reverse:

Suppose result is 18.

What number plus or minus 13 gives 18?

18 - 13 = 5 → so (7 □ 2) must be 5.

So: 7 □ 2 = 5 → 7 - 2 = 5 ✔

Then: (7 - 2) + 13 = 5 + 13 = 18 ✔

So: (7 - 2) + 13 = 18

✔ Answer: - and +

4. (11 □ 10) □ (12 □ 6) = 19

Try possibilities.

Try:
- 11 + 10 = 21 → 12 ÷ 6 = 2 → 21 - 2 = 19 ✔

So: (11 + 10) - (12 ÷ 6) = 21 - 2 = 19

✔ Answer: +, -, ÷

But we have three boxes. So:
(11 + 10) - (12 ÷ 6) = 19

So: +, -, ÷

✔ Answer: +, -, ÷

---

5. (12 □ 18) □ 13 = -78

Try:
12 + 18 = 30 → 30 - 13 = 17 ✘
12 - 18 = -6 → -6 × 13 = -78 ✔

So: (12 - 18) × 13 = (-6) × 13 = -78

✔ Answer: -, ×

---

6. 12 □ (20 □ 27) = -84

Try:
20 + 27 = 47 → 12 - 47 = -35 ✘
20 - 27 = -7 → 12 × (-7) = -84 ✔

So: 12 × (20 - 27) = 12 × (-7) = -84

✔ Answer: ×, -

---

7. (23 □ 30) □ 17 = -119

Try:
23 + 30 = 53 → 53 - 17 = 36 ✘
23 - 30 = -7 → -7 × 17 = -119 ✔

So: (23 - 30) × 17 = (-7) × 17 = -119

✔ Answer: -, ×

8. (14 □ 30) □ (21 □ 13) = 1496

Try:
Look at 1496. Let’s see what could multiply to give this.

Try: 14 × 30 = 420 → too small

14 + 30 = 44 → 21 + 13 = 34 → 44 × 34 = ?

44 × 34 = (40+4)(30+4) = 40×30=1200, 40×4=160, 4×30=120, 4×4=16 → total = 1200+160+120+16 = 1496 ✔

So: (14 + 30) × (21 + 13) = 44 × 34 = 1496

✔ Answer: +, ×, +

---

9. (39 □ 40) □ 73 = 152

Try:
39 + 40 = 79 → 79 + 73 = 152 ✔

So: (39 + 40) + 73 = 79 + 73 = 152

✔ Answer: +, +

---

10. (36 □ 39) □ (30 □ 33) = 4725

Try:
36 × 39 = ? → 36×40 = 1440 → minus 36 = 1404

30 × 33 = 990

1404 × 990 → way too big

Try: 36 + 39 = 75

30 + 33 = 63

75 × 63 = ?

75 × 60 = 4500
75 × 3 = 225
Total = 4500 + 225 = 4725 ✔

So: (36 + 39) × (30 + 33) = 75 × 63 = 4725

✔ Answer: +, ×, +

1. (24 × 9) + 1 = 217 → ×, +
2. 32 × (5 + 10) = 480 → ×, +
3. (7 - 2) + 13 = 18 → -, +
