### Associative Property of Addition: Interactive Exercise

**Instructions:**

In this exercise, you will practice applying the Associative Property of Addition by supplying reasons for each step of the calculation.

**Example Problem:**  
Simplify the expression \((625 + 38) + 75\).

1. Starting Expression:
   \[
   (625 + 38) + 75
   \]
   Apply the Associative Property of Addition:
   \[
   = 625 + (38 + 75)
   \]

2. Evaluate the expression within the parentheses:
   \[
   = 625 + (75 + 38)
   \]

3. Simplify further by switching the associative grouping:
   \[
   = (625 + 75) + 38
   \]

4. Add the numbers within the new grouping:
   \[
   = 700 + 38
   \]

5. Calculate the final sum:
   \[
   = 738
   \]

**Interactive Question:**

Choose the correct reason for each step in the given problem by selecting from the dropdown options.

1. \((625 + 38) + 75 = 625 + (38 + 75)\)  
   \[ \boxed{\text{Select Reason}} \]

2. \(625 + (38 + 75) = 625 + (75 + 38)\)  
   \[ \boxed{\text{Select Reason}} \]

3. \(625 + (75 + 38) = (625 + 75) + 38\)  
   \[ \boxed{\text{Select Reason}} \]

4. \( (625 + 75) + 38 =  700 + 38\)  
   \[ \text{Simplify Addition} \]

5. \(700 + 38 = 738\)  
   \[ \text{Simplify Addition} \]

*Note: Steps 4 and 5 show the arithmetic calculation of adding the numbers within the groupings and their final sum, and do not require selecting reasons.*
