Answer 1

To solve the given expression, let's break it down step by step:

1. Start by evaluating the expression inside the parentheses: 135 * 3 - 198 = 405 - 198 = 207.

2. Now substitute the result back into the original expression: 756 - 207 + 406 * 12 - 840.

3. Next, perform the multiplication: 406 * 12 = 4872.

4. Now substitute the multiplication result back into the expression: 756 - 207 + 4872 - 840.

5. Finally, perform the addition and subtraction from left to right: 756 - 207 + 4872 - 840 = 549 + 4872 - 840 = 5421 - 840 = 4581.

Therefore, the solution to the given expression is 4581.
