1. Solve $11 + 3^3 - 7$: Calculate the exponent first: $3^3 = 27$. Then perform addition and subtraction from left to right: $11 + 27 - 7 = 31$. 2. Solve $5^2 - 7 \times 2$: Calculate the exponent: $5^2 = 25$. Calculate multiplication: $7 \times 2 = 14$. Subtract: $25 - 14 = 11$. 3. Solve $2^2 + 8 \div 4$: Calculate the exponent: $2^2 = 4$. Calculate division: $8 \div 4 = 2$. Add: $4 + 2 = 6$. 4. Solve $6^2 \times 3 \div 9$: Calculate the exponent: $6^2 = 36$. Multiply: $36 \times 3 = 108$. Divide: $108 \div 9 = 12$. 5. Solve $6 + 6^3 - 12$: Calculate the exponent: $6^3 = 216$. Add and subtract from left to right: $6 + 216 - 12 = 210$. 6. Solve $8 \times 12^3 + 11$: Calculate the exponent: $12^3 = 1728$. Multiply: $8 \times 1728 = 13824$. Add: $13824 + 11 = 13835$. 7. Solve $8^2 \times 2 \div 4$: Calculate the exponent: $8^2 = 64$. Multiply: $64 \times 2 = 128$. Divide: $128 \div 4 = 32$. 8. Solve $7^3 + 12 \div 3$: Calculate the exponent: $7^3 = 343$. Divide: $12 \div 3 = 4$. Add: $343 + 4 = 347$. 9. Solve $3 + 9^2 - 5$: Calculate the exponent: $9^2 = 81$. Add and subtract from left to right: $3 + 81 - 5 = 79$. 10. Solve $5 + 9 \times 3^3$: Calculate the exponent: $3^3 = 27$. Multiply: $9 \times 27 = 243$. Add: $5 + 243 = 248$. 11. Solve $6^3 - 4^2 + 8$: Calculate the exponents: $6^3 = 216$, $4^2 = 16$. Subtract and add from left to right: $216 - 16 + 8 = 208$. 12. Solve $7 + 1^3 - 8$: Calculate the exponent: $1^3 = 1$. Add and subtract from left to right: $7 + 1 - 8 = 0$.
