3-Digit Subtraction without Regrouping

In 1st grade, we have learnt the subtraction of 1-digit and 2-digit numbers. Here, we will learn simple subtraction of 3-digit numbers without regrouping (borrowing).

We subtract 3-digit numbers in the same way as we subtract 2-digit numbers.

Let us subtract 345 from 689.

To perform the above subtraction, we take the following steps:

Step I: Write the given numbers in column form as shown.

Step II: Subtract the ones:

9 - 5 = 4

Write 4 under ones column.


Step III: Subtract the ten

8 - 4 = 4

Write 4 under tens column.


Step IV: Subtract the hundreds:

6 - 3 = 3

Write 3 under hundreds column.

Thus, the difference between 689 and 345 is 344.
