Answer 3

To solve the expression (2009 - 789) - (374 + 159) + (907 - 368), you can follow the order of operations, which is typically remembered using the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

Let's break it down step by step:

1. Inside the first set of parentheses: 2009 - 789 = 1220

2. Inside the second set of parentheses: 374 + 159 = 533

3. Inside the third set of parentheses: 907 - 368 = 539

Now, your expression looks like this: (1220) - (533) + (539)

4. Subtract the second set of parentheses from the first set: 1220 - 533 = 687

5. Finally, add the result to the third set of parentheses: 687 + 539 = 1226

So, the final answer to the expression (2009 - 789) - (374 + 159) + (907 - 368) is 1226.
