Let's solve each problem step by step. These involve
square numbers, which means we are squaring the numbers (multiplying them by themselves) and then adding or subtracting.

1. $3^2 + 4^2 = ?$
- $3^2 = 3 \times 3 = 9$
- $4^2 = 4 \times 4 = 16$
- $9 + 16 = 25$
✔ Answer: 25

2. $10^2 + 8^2 = ?$
- $10^2 = 10 \times 10 = 100$
- $8^2 = 8 \times 8 = 64$
- $100 + 64 = 164$
✔ Answer: 164

3. $13^2 + 10^2 = ?$
- $13^2 = 13 \times 13 = 169$
- $10^2 = 10 \times 10 = 100$
- $169 + 100 = 269$
✔ Answer: 269
---
4. $20^2 + 5^2 = ?$
- $20^2 = 20 \times 20 = 400$
- $5^2 = 5 \times 5 = 25$
- $400 + 25 = 425$
✔ Answer: 425

5. $15^2 - 9^2 = ?$
- $15^2 = 15 \times 15 = 225$
- $9^2 = 9 \times 9 = 81$
- $225 - 81 = 144$
✔ Answer: 144
---
6. $17^2 - 10^2 = ?$
- $17^2 = 17 \times 17 = 289$
- $10^2 = 100$
- $289 - 100 = 189$
✔ Answer: 189
---
7. $18^2 - 14^2 = ?$
- $18^2 = 18 \times 18 = 324$
- $14^2 = 14 \times 14 = 196$
- $324 - 196 = 128$
✔ Answer: 128
---
8. $20^2 - 12^2 = ?$
- $20^2 = 400$
- $12^2 = 12 \times 12 = 144$
- $400 - 144 = 256$
✔ Answer: 256
