4 Subtraction of 4-Digit Numbers

Warm Up

● Subtraction means taking away a number or a quantity from a given number or quantity. The
result of subtraction is known as the diff erence.
● In previous class, we have learnt how to subtract 2-digit and 3-digit numbers.
● To subtract 2-digit or 3-digit numbers we always write the larger number fi rst and then fi nd

Subtraction of 4-digit Numbers Without Borrowing

Subtraction of 4-digit numbers is similar to subtraction of 3-digit numbers.

For subtracting a given number from another number, we write the larger number fi rst
in the columns, then the smaller number and fi nd the diff erence for each place starting
from ones, then tens, then hundreds and fi nally thousands.

Let's Try

Example 1: Subtract 6342 from 8573.

Solution: Here 8573 > 6342

Arrange the numbers in columns and then follow these steps:

Step-1: Subtract the ones. Step-2: Subtract the tens.

3 – 2 = 1 one 7 – 4 = 3 tens

Write 1 under ones column. Write 3 under tens column.

Step-3: Subtract the hundreds.
Minuend
5 – 3 = 2 hundreds
Th H T O
Write 2 under hundreds column. 8 5 7 3

Step-4: Subtract the thousands. – 6 3 4 2

8 – 6 = 2 thousands 2 2 3 1

Write 2 under thousands column. Diff erence

Hence, the diff erence is 2231.
