We have several worked examples so you can see how to work out different additions step-by-step.

We also have a range of worksheets suitable for different levels of ability.

• understand how to do 3-digit addition
• set out an addition problem correctly.

## How to do 3-Digit Addition

Step 1) Add the Ones digit of both numbers together.

• Write the number of Ones below the line in the Ones place.
• If the total of the two digits is 10 or more, then regroup the 10 Ones into 1 Ten and move it into the Tens column.

We add the Ones: 5 + 8 = 13 Ones.

We regroup the 13 Ones into 1 Ten and 3 Ones.

We carry over 1 Ten and move it to the top of the Tens column.

We write a 3 under the line in the Ones place.

Step 2) Add the Tens digit of both numbers together, remember to add any Tens that were carried over.

• Write the number of Tens below the line in the Tens place.
• If the total of the two digits is 10 or more, then regroup the 10 Tens into 1 Hundred and move it into the Hundreds column.

We add the Tens, including the Ten we carried over: 1 + 2 + 1 = 4 Tens.

We write this number under the line in the Tens place.

Step 3) Add the Hundreds digit of both numbers together, remember to add any Hundreds that were carried over.

• Write the number of Hundreds below the line in the Hundreds place.
• If the total of the two digits is 10 or more, then regroup the 10 Hundreds into 1 Thousand and write it into the Thousands place.

We add the Hundreds: 6 + 4 = 10 Hundreds.

We regroup the 10 Hundreds into 1 Thousand and 0 Hundreds.

As there are no further digits to add up, we write the 1 in the Thousands place and a 0 in the Hundreds place.

## Example 1) Work out 247 + 132.

This example does not need any regrouping.

Adding the Ones gives us: 7 + 2 = 9 Ones. We write this below the line in the Ones place.

Adding the Tens gives us: 4 + 3 = 7 Tens. We write this below the line in the Tens place.

Adding the Hundreds gives us: 2 + 1 = 3 Hundreds. We write this below the line in the Hundreds place.

This gives us a final answer of 247 + 132 = 379

## Example 2) Work out 506 + 248.

Adding the Ones gives us: 6 + 8 = 14 Ones = 1 Ten + 4 Ones. Write the 4 Ones below the line in the Ones place. Carry over the 1 Ten into the Tens column.

Adding the Tens gives us: 1 + 0 + 4 = 5 Tens. We write this below the line in the Tens place

Adding the Hundreds gives us: 5 + 2 = 7 Hundreds. We write this below the line in the Hundreds place.

This gives us a final answer of 506 + 248 = 754

## Example 3) Work out 482 + 176.

Adding the Ones gives us: 2 + 6 = 8 Ones. We write this below the line in the Ones place.

Adding the Tens gives us: 8 + 7 = 15 Tens = 1 Hundred + 5 Tens. We write 5 Tens below the line in the Tens place. We carry 1 Hundred into the Hundreds column.

Adding the Hundreds gives us: 1 + 4 + 1 = 6 Hundreds . We write this below the line in the Hundreds place.

This gives us a final answer of 482 + 176 = 658

## Example 4) Work out 974 + 389

Adding the Ones gives us: 4 + 9 = 13 Ones = 1 Ten + 3 Ones. We write 3 Ones below the line in the Ones place and carry over 1 Ten into the Tens column.

Adding the Tens gives us: 1 + 7 + 8 = 16 Tens = 1 Hundred + 6 Tens. We write 6 Tens below the line in the Tens place. We carry 1 Hundred into the Hundreds column.

Adding the Hundreds gives us: 1 + 9 + 3 = 13 Hundreds = 1 Thousand + 3 Hundreds .

We write 1 in the Thousands place and 3 in the Hundreds place.

This gives us a final answer of 974 + 389 = 1363

## Example 5) Work out 728 + 457 + 66

Step 1) Add the Ones digit of the 3 numbers together.

Adding the Ones gives us: 8 + 7 + 6 = 21 Ones = 2 Tens + 1 One. We write 1 One below the line in the Ones place and carry over 2 Tens into the Tens column.

Step 2) Add the Tens digit of the 3 numbers together, remember to add any Tens that were carried over.

Adding the Tens gives us: 2 + 2 + 5 + 8 = 17 Tens = 1 Hundred + 7 Tens. We write 7 Tens below the line in the Tens place. We carry 1 Hundred into the Hundreds column.

Step 3) Add the Hundreds digit of the 3 numbers together, remember to add any Hundreds that were carried over.

Adding the Hundreds gives us: 1 + 7 + 4 = 12 Hundreds = 1 Thousand + 2 Hundreds.

We write 1 in the Thousands place and 2 in the Hundreds place.

This gives us a final answer of 728 + 457 + 86 = 1271
