# Example of Subtraction

Subtracting Tens

• First line up the numbers as per the place value (all the tens and the units lined up vertically). Put a line under the last number.
• ```40
30
```
• Subtract the ones place numbers. (0 - 0 = 0). Write the zero in the ones place column.
• ```40
30
0
```
• Subtract the tens place digits (4 - 3 = 1) and write the answer below the line in the tens place column.
• ```40
30
10```

Subtracting Two Digit Numbers

How to subtract two-digit numbers (for example 75 - 43).
• First line up the numbers as per the place value (all the tens and the units lined up vertically). Draw a line under the last number.
• ```75
43
```
• Subtract the numbers in the ones place. (5-3=2) and write the 2 below the line in the ones place column.
• ```75
43
2
```
• Subtract the digits in the tens place column (7-4 = 3) and write the answer below the line in the tens place column.
• ```75
43
32```

Note: If the ones place number you are subtracting is greater than the top ones place number, then decrease the top tens place number by 1 and increase the top ones place value by 10 before subtracting.

Subtracting Three Digit Numbers

How to subtract three digit numbers (for example 746 - 463)?

• First line up the numbers as per the place value (all the hundreds,tens and the ones lined up vertically). Draw a line under the last number.
• ```746
463
```
• Subtract the numbers in the ones place column (6 - 3 = 3) and write the answer in the ones place column.
• ```
746
463
3
```
• Subtract the digits in the tens place column (4 - 6 =?). Borrow 1 from the hundreds place to make the top tens place value greater than the bottom tens place value. After this is done, subtract (14 - 6 = 8) and write the 8 below the line in the tens place column.
• ```6
746
463
83```
• Subtract the numbers in the hundreds place column (6 - 4 = 2) and write the answer below the line in the hundreds place column.
• ```6
746
463
283```

Subtracting Hundreds

• First line up the digits as per the place value (all the hundreds, tens and the ones lined up vertically). Draw a line under the bottom number.
• ```400
300
```
• Subtract the numbers in the ones place digits. (0 - 0 = 0) and write the answer below the line in the ones place column.
• ```
400
300
0
```
• Subtract the tens place numbers (0 - 0 = 0) and place the answer below the line and to the tens place column
• ``` 400
300
00```
• Subtract the digits in the hundreds place column (4- 3 = 1) and write the answer below the line in the hundreds place column.
• ```  400
300
100```
Subtraction facts for 0, 1 and 2

The Subtraction facts for 0, 1 and 2 are in the following table.

 ZERO 0-0=0 1-0=1 2-0=2 3-0=3 4-0=4 ONE 1-1=0 2-1=1 3-1=2 4-1=3 5-1=4 TWO 2-2=0 3-2=1 4-2=2 5-2=3 6-2=4

When 0 is subtracted to a first digit the answer is the first digit. (e.g. 6-0 = 6)

Subtracting 1 to any number is like decreasing by 1.

Subtracting 2 to any number is like decreasing by 2.

Mentally Subtracting Two-Digit Numbers

How to mentally subtract two-digit numbers?

Subtract 44 from 93.

• First subtract the two tens place numbers (9 - 4 = 5)
• If the bottom ones place number is greater than the top ones place number then decrease the answer for the tens digit by one (5 - 1 = 4) and increase the top ones place digit by 10 (3 + 10 = 13). Now subtract the two ones place numbers (13 - 4 = 9). Write the answer 49.

Subtract 62 from 84.

• First subtract the numbers in the tens place (8-6 = 2)
• Subtract the numbers in the ones place (4 - 2 = 2)
• Write the answer of 22
