Addition of 3-Digit Numbers with Regrouping

We will learn addition of 3-digit numbers with regrouping.

Addition of 3-Digit Numbers with Regrouping

1. Add 495 and 65.

Solution:

Step 1: Arrange the numbers vertically.

Step 2: Add the ones. 5 + 5 = 10 ones = 1 ten and 0 one. Write 0 in the ones column and carry over 1 to the tens column.

Step 3: Add the tens. 9 + 6 + 1 (carry over) = 16 tens = 1 hundred and 6 tens. Write 6 in the tens column and carry over 1 to the hundreds column.

Step 4: Add the hundreds. 4 +1 (carry over) = 5 hundreds. Write 5 in the hundreds column.

Thus, 495 + 65 = 560



2. Add 379 and 558

Solution:

Step 1: Arrange the numbers vertically.

Step 2: Add the ones column. 9 + 8 = 17 ones = 1 ten and 7 ones. Write 7 in the ones column and carry over 1 to the tens column.

Step 3: Add the tens column. 7 + 5 + 1 (carry over) = 13 tens = 1 hundred and 3 tens. Write 3 in the tens column and carry over 1 to the hundreds column.

Step 4: Add the hundreds column. 3 + 5 + 1 (carry over) = 9 hundreds.
