### How to do 3 Digit Subtraction

#### How to do 3-Digit Subtraction

Step 1) Subtract the Ones digit of the subtrahend from the Ones digit of the minuend.

• Write the number of Ones below the line in the Ones place.
• If the Ones digit underneath is greater than the Ones digit above then take a ten from the minuend and convert it into 10 ones.
• If the Ones digit underneath is greater and there are no Tens in the minuend, then take one Hundred from the minuend and convert it into 10 Tens. Then take one of the tens and convert it into 10 Ones.

We exchange one Ten into 10 Ones. There is now 1 Ten and 13 Ones.
Now we can subtract the Ones: 13 - 6 = 7

Step 2) Subtract the Tens digit of the subtrahend from the Tens digit of the minuend.

• Write the number of Tens below the line in the Tens place.
• If the tens digit underneath is greater than the ones digit above then take a ten from the minuend and convert it into 10 tens.

We exchange one Hundred into 10 Tens. There are now 7 Hundreds and 11 Tens.
Now we can subtract the Tens: 11 - 9 = 2

Step 3) Subtract the Hundreds digit of the subtrahend from the Hundreds digit of the minuend.

• Write the number of Hundreds below the line in the Hundreds place.

Subtracting the Hundreds gives us: 7 - 4 = 3

This gives us a final answer of 823 - 496 = 327

### 3 Digit Subtraction Worked Examples

#### Example 2) Work out 327 - 154.

Step 1) Subtract the Ones digit of the subtrahend from the Ones digit of the minuend.

Subtracting the Ones gives us: 7 - 4 = 3

Step 2) Subtract the Tens digit of the subtrahend from the Tens digit of the minuend.

• If the tens digit underneath is greater than the ones digit above then take a ten from the minuend and regroup it into 10 tens.

We need to take 1 Hundred and regroup it into 10 Tens. We now have 2 Hundreds and 12 Tens.

Now we can subtract the Tens: 12 - 5 = 7

Step 3) Subtract the Hundreds digit of the subtrahend from the Hundreds digit of the minuend.

Subtracting the Hundreds gives us: 2 - 1 = 1.

This gives us a final answer of 327 - 154 = 173

#### Example 3) Work out 861 - 639.

Step 1) Subtract the Ones digit of the subtrahend from the Ones digit of the minuend.

• If the Ones digit underneath is greater than the Ones digit above then take a ten from the minuend and regroup it into 10 ones.

We need to take 1 Ten and regroup it into 10 Ones. We now have 5 Tens and 11 Ones.

Now we can subtract the Ones: 11 - 9 = 2

Step 2) Subtract the Tens digit of the subtrahend from the Tens digit of the minuend.

Subtracting the Tens gives us: 5 - 3 = 2

Step 3) Subtract the Hundreds digit of the subtrahend from the Hundreds digit of the minuend.

Subtracting the Hundreds gives us: 8 - 6 = 2.

This gives us a final answer of 861 - 639 = 222

#### Example 4) Work out 602 - 375.

Step 1) Subtract the Ones digit of the subtrahend from the Ones digit of the minuend.

• If the Ones digit underneath is greater and there are no Tens in the minuend, then take one Hundred from the minuend and regroup it into 10 Tens. Then take one of the tens and regroup it into 10 Ones.

We need to take 1 Ten and regroup it into 10 Ones. Since there are no Tens, we need to take 1 Hundred and regroup it into 10 Tens.

We now have 5 Hundreds and 10 Tens.

We can now take 1 Ten and regroup it into 10 Ones. We now have 5 Hundred, 9 Tens and 12 Ones.

We can now subtract the Ones: 12 - 5 = 7

Step 2) Subtract the Tens digit of the subtrahend from the Tens digit of the minuend.

Subtracting the Tens gives us: 9 - 7 = 2

Step 3) Subtract the Hundreds digit of the subtrahend from the Hundreds digit of the minuend.

Subtracting the Hundreds gives us: 5 - 3 = 2.

This gives us a final answer of 602 - 375 = 227
