Here are the detailed solutions for each expression:

8. For the expression $$ 15 - 7 	imes 2 + 2^{3} $$:
   - First, calculate $$ 7 	imes 2 = 14 $$.
   - Then, calculate $$ 2^{3} = 8 $$.
   - Now substitute back into the expression: $$ 15 - 14 + 8 $$.
   - Perform the operations from left to right: $$ 15 - 14 = 1 $$ and then $$ 1 + 8 = 9 $$.
   - **Final result:** $$ 9 $$.

10. For the expression $$ 6 + 3(13 - 2) - 5^{2} $$:
   - First, calculate $$ 13 - 2 = 11 $$.
   - Then, calculate $$ 3 	imes 11 = 33 $$.
   - Next, calculate $$ 5^{2} = 25 $$.
   - Now substitute back into the expression: $$ 6 + 33 - 25 $$.
   - Perform the operations from left to right: $$ 6 + 33 = 39 $$ and then $$ 39 - 25 = 14 $$.
   - **Final result:** $$ 14 $$.

12. For the expression $$ \frac{8 + 6^{2}}{11} + 7 	imes 2 $$:
   - First, calculate $$ 6^{2} = 36 $$.
   - Then, calculate $$ 8 + 36 = 44 $$.
   - Now calculate $$ \frac{44}{11} = 4 $$.
   - Next, calculate $$ 7 	imes 2 = 14 $$.
   - Substitute back into the expression: $$ 4 + 14 $$.
   - Perform the final addition: $$ 4 + 14 = 18 $$.
   - **Final result:** $$ 18 $$.

In summary:
- Expression 8: $$ 9 $$
- Expression 10: $$ 14 $$
- Expression 12: $$ 18 $$
- Expression 8: 9 - Expression 10: 14 - Expression 12: 18

8. \( 15-7 \times 2+2^{3} \) 10. \( 6+3(13-2)-5^{2} \) 12. \( \frac{8+6^{2}}{11}+7 \times 2 \)
