**Addition of Three 3-digit numbers with Regrouping**

**Example 1:- Add the following?**

**Explanation:**

**Step 1: Adding the digits at one’s place,**

**7 + 5 + 6 = 18**

**Since the number is more than 9, we need to carry over 1 to the tens place.**

**Step 2: Adding the digits at tens place and the carry of 1,**

**2 + 4 + 5 + 1 = 12**

**Since the number is more than 9, we need to carry over 1 to the hundreds place.**

**Step 3: Adding the digits at hundreds place and carry 1,**

**3 + 2 + 2 + 1 = 8**

**Hence, the sum of the given numbers is 828**

**Example 2:- Add the following?**

**Step 1: Adding the digits at one’s place,**

**5 + 3 + 2 = 10**

**Since the number is more than 9, we need to carry over 1 to the tens place.**

**Step 2: Adding the digits at tens place and the carry of 1,**

**7 + 9 + 0 + 1 = 17**

**Since the number is more than 9, we need to carry over 1 to the hundreds place.**

**Step 3: Adding the digits at hundreds place and carry 1,**

**2 + 5 + 1 + 1 = 9**

**Hence, the sum of the given numbers is 970**

**Example 3:- Add the following?**

**Explanation:**

**Step 1: Adding the digits at one’s place,**

**5 + 2 + 5 = 12**

**Since the number is more than 9, we need to carry over 1 to the tens place.**

**Step 2: Adding the digits at tens place and the carry of 1,**

**8 + 7 + 2 + 1 = 18**

**Since the number is more than 9, we need to carry over 1 to the hundreds place.**

**Step 3: Adding the digits at hundreds place and carry 1,**

**2 + 4 + 2 + 1 = 9**

**Hence, the sum of the given numbers is 982**
