2. 3
3. 35
4. 9
5. 24
6. 10

Explicación paso a paso:

• $8 \times 3 - (6 - 3) + 7 \\ 24 - (3) + 7 \\ 21 + 7 \\ 28$
• $(12 + 8) \div 2 - (10 - 3) \\ 20 \div 2 - 7 \\ 10 - 7 \\ 3$
• $25 + 7 + 40 \div 5 - (10 - 5) \\ 32 + 40 \div 5 - 5 \\ 32 + 8 - 5 \\ 35$
• $(12 + 8 + 20 - 10) \times 3 \div (25 - 15) \\ (20 + 20 - 10) \times 3 \div 10 \\ 30 \times 3 \div 10 \\ 30 \times 0.3 \\ 9$
• $(5 + 8 + 3) \div 4 \times (12 - 6) \\ 16 \div 4 \times 6 \\ 4 \times 6 \\ 24$
• $(52 + 11) \div 9 + (15 \div 5) \\ 63 \div 9 + 3 \\ 7 + 3 \\ 10$
