Answer 2

To simplify the expression -a - (-2a-(4a-(-a - 1))), you can follow these steps:

1. Start by simplifying the innermost parentheses first: -a - (-2a - (4a - (-a - 1)))

2. Remove the double negatives by changing the signs within the innermost parentheses: -a - (-2a - 4a + a + 1)

3. Combine like terms within the parentheses: -a - (-5a + 1)

4. Distribute the negative sign outside the parentheses: -a + 5a - 1

5. Combine like terms: 4a - 1

So, the simplified expression is 4a - 1.
