Answer 3

Let's solve each of these expressions step by step:

1. 125 + ((-125) + 25) First, we evaluate the expression inside the innermost parentheses: -125 + 25 = -100

   Now, we can add this result to the outermost expression: 125 + (-100) = 25

2. 149 - (126 - (-70)) First, we evaluate the expression inside the innermost parentheses: -(-70) is equivalent to 70, so: 126 - (-70) = 126 + 70 = 196

   Now, we can subtract this result from the outermost expression: 149 - 196 = -47

3. 202 + ((-38) + 102) First, we evaluate the expression inside the innermost parentheses: -38 + 102 = 64

   Now, we can add this result to the outermost expression: 202 + 64 = 266

So, the answers are:

1. 25
2. -47
3. 266
