Let A =Σ_i=1^10 Σ_j=1^10 min {i, j} and B =Σ_i=1^10 Σ_j=1^10 max {i, j}. Then A + B is equal to \ \ \ \.
Let $\displaystyle \mathrm{A}=\sum_{i=1}^{10} \sum_{j=1}^{10} \min \{i, j\}$ and $\displaystyle \mathrm{B}=\sum_{i=1}^{10} \sum_{j=1}^{10} \max \{i, j\}$. Then $\displaystyle \mathrm{A}+\mathrm{B}$ is equal to \_\_\_\_.
