In subtracting 1-digit quantity we are going to

subtract or minus one-digit quantity from one-digit quantity or one-digit quantity from 2-digit quantity and discover the distinction between them.

We all know that subtraction means to take away a set of objects from a set.

We use **– **signal to remove

9 – 6 = 3

We are saying that distinction between 9 and 6 is 3.

After we subtract 0 from a quantity, the quantity stays the identical.

After we subtract the quantity from itself we get 0.

If from six issues we take away 2 issues, then 4 issues are left. In arithmetic that is written in a brief method as follows:

6 – 2 = 4

The image – known as the **minus** signal and exhibits that the quantity written after it’s to be **subtracted**, or taken away, from the quantity written earlier than it.

We might learn 6 – 2 = 4 as ‘**six minus two is the same as 4**’ or ‘**six much less two is 4**’.

We’ve got learnt that we are able to subtract numbers by counting backward.

8 – 3 = ?

Counting backward from 8, take jumps backward. You attain 5.

How one can subtract two one-digit numbers?

**1.** Right here we are going to discover 2 – 1.

Observe the steps together with the image:

(i) 2 – 1 means begin 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) Subsequently, 2 – 1 = 1

We might learn 2 – 1 = 1

as ‘**two minus one is the same as one**’

or ‘**two much less one is one**’.

**2.** Right here we are going to discover 5 – 3.

Observe the steps of subtracting 1-digit quantity together with the image:

(i) 5 – 3 means begin 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) Subsequently, 5 – 3 = 2

We might learn 5 – 3 = 2

as ‘**5 minus three is the same as two**’

or ‘**5 much less three is 2**’.

**3.**

Right here we are going to discover 7 – 2.

Observe the steps alongside

with the image:

(i) 7 – 2 means begin 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) Subsequently, 7 – 2 = 5

We might learn 7 – 2 = 5

as ‘**seven minus two is the same as 5**’

or ‘**seven much less two is 5**’.

**4.**

Right here we are going to discover 9 – 5.

Observe the steps of subtracting

1-digit quantity together with the image:

(i) 9 – 5 means begin 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) Subsequently, 9 – 5 = 4

We might learn 9 – 5 = 4 as

‘**9 minus 5 is the same as 4**’

or ‘**9 much less 5 is 4**’.

**5.**

Right here we are going to discover 8 – 8.

Observe the steps of the subtraction of 1-digit quantity together with the

image:

(i) 8 – 8 means begin 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) Subsequently, 8 – 8 = 0

We might learn 8 – 8 = 0 as ‘**eight minus eight is the same as zero**’ or ‘**eight much less eight is zero**’.

**SUBTRACTION PROPERTIES**

Allow us to study the properties of subtraction.

**Subtraction of 0**

What do you get once you subtract 0 from a quantity?

When 0 is subtracted from a quantity, the distinction is the quantity itself.

**Attempt This!**

**Fill within the containers.**

6 – 0 = _____

5 – 0 = _____

_____ – 0 = 7

9 – _____ = 9

**Subtraction of 1**

What do you get once you subtract 1 from a quantity?

When 1 is subtracted from a quantity, the distinction is the earlier quantity.

**Attempt This!**

**Fill within the containers.**

5 – 1 = _____

8 – 1 = _____

_____ – 1 = 7

9 – _____ = 8
