Following the princess' first game, her little sister, Princess Bella, wanted to join in with her own twist. Bella did as follows:

In the first round, Bella copied Anna and added the same two numbers: 7 and 10 together.

For the second round, sister Bella thought of the number 33. Just like Anna, She subtracted the result from the first round and then decreased it by 8.

In the final round, Princess Bella, like Anna, added the results from the first and second round. Then, she multiplied the sum by the result from her modified second round. What was the final result of Princess Bella's game?
