Subtracting 1-Digit Number

In subtracting 1-digit number we will subtract or minus two one-digit number and find the difference between them.

If from six things we take away 2 things, then four things are left. In arithmetic this is written in a short way as follows:

6 – 2 = 4

The symbol – is called the minus sign and shows that the number written after it is to be subtracted, or taken away, from the number written before it.

We may read 6 – 2 = 4 as ‘six minus two is equal to four’ or ‘six less two is four’.

How to subtract two one-digit numbers?

1. Here we will find 2 – 1.

Follow the steps along with the picture:

(i) 2 – 1 means start with 2 and take away 1.

(ii) From 2 strokes we take away 1 stroke and cancel the strokes.

(iii) So, 1 stroke is left.

(iv) Therefore, 2 – 1 = 1

We may read 2 – 1 = 1 as ‘two minus one is equal to one’ or ‘two less one is one’.

2. Here we will find 5 – 3.

Follow the steps of subtracting 1-digit number along with the picture:

(i) 5 – 3 means start with 5 and take away 3.

(ii) From 5 strokes we take away 3 strokes and cancel the strokes.

(iii) So, 2 strokes are left.

(iv) Therefore, 5 – 3 = 2

We may read 5 – 3 = 2 as ‘five minus three is equal to two’ or ‘five less three is two’.

3. Here we will find 7 – 2.

Follow the steps along with the picture:

(i) 7 – 2 means start with 7 and take away 2.

(ii) From 7 strokes we take away 2 strokes and cancel the strokes.

(iii) So, 5 strokes are left.

(iv) Therefore, 7 – 2 = 5

We may read 7 – 2 = 5 as ‘seven minus two is equal to five’ or ‘seven less two is five’.

4. Here we will find 9 – 5.

Follow the steps of subtracting 1-digit number along with the picture:

(i) 9 – 5 means start with 9 and take away 5.

(ii) From 9 strokes we take away 5 strokes and cancel the strokes.

(iii) So, 4 strokes are left.

(iv) Therefore, 9 – 5 = 4

We may read 9 – 5 = 4 as ‘nine minus five is equal to four’ or ‘nine less five is four’.

5. Here we will find 8 – 8.

Follow the steps of the subtraction of 1-digit number along with the picture:

(i) 8 – 8 means start with 8 and take away 8.

(ii) From 8 strokes we take away 8 strokes and cancel the strokes.

(iii) So, 0 strokes are left.

(iv) Therefore, 8 – 8 = 0

We may read 8 – 8 = 0 as ‘eight minus eight is equal to one’ or ‘eight less eight is one’.
