Answer 3

To simplify the expression and remove the parentheses, follow the order of operations, which is:

1. Perform operations inside innermost parentheses first.
2. Then work your way outward to handle other operations.

Let's start by solving the expression step by step:

1. First, let's simplify the expression inside the innermost parentheses: (1 - (2 - m)) To do this, perform the subtraction inside the parentheses: 1 - (2 - m) = 1 - 2 + m = -1 + m

Now, the original expression becomes: 3m + (-1 + m)

2. Next, combine like terms by adding 'm' and '3m': 3m + (-1 + m) = 3m - 1 + m

3. Finally, combine the remaining 'm' terms: 3m - 1 + m = 4m - 1

So, the simplified expression after removing the parentheses is: 4m - 1
