Subtracting 1-Digit Quantity | Subtract or Minus Two One-Digit Quantity

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’.
