### Subtracting 2-Digit Numbers | The right way to Subtract Two Digit Numbers?

In subtracting 2-digit numbers we’ll subtract or minus a onedigit quantity from one other twodigit quantity and a twodigit quantity from one other twodigit quantity. To seek out the distinction between
the 2 numbers we have to ‘ones from ones’ and ‘tens from tens’.

Allow us to subtract 2 from 39

 = 37 ones = 3 tens + 7 ones
 Subtract ones and write within the ones place. 9 ones – 2 ones = 7 ones Subtract tens and write within the tens place. 3 tens – 0 tens = 3 tens

39 – 2 = 37

Allow us to subtract 34 from 65.

 = 31 ones = 3 tens + 1 one
 Subtract ones and write within the ones place. 5 ones – 4 ones = 1 ones Subtract tens and write within the tens place. 6 tens – 3 tens = 3 tens

65 – 34 = 31

The right way to subtract two digit numbers?

The steps of the examples on subtracting 2-digit numbers i.e. ‘ones from ones’ and ‘tens from tens’:

1. Subtract 41
from 63.

(i) First prepare the
numbers vertically in order that the tens’ place digits and ones’ place digits are
lined up which suggests in easy one quantity ought to be written above the opposite
quantity. Draw a line beneath the underside quantity.

(ii) Subtract the digits within the ones place. Subtract (3
– 1 = 2). Place 2 within the ones column as proven.

(iii) Subtract the digits within the tens’ place. Subtract (6 –
4 = 2). Place 2 within the tens column as proven.

(iv) The distinction of 63 – 41 is 22

2. Subtract 52 from 86.

(i) First prepare the numbers vertically in order that the tens’ place digits and ones’ place digits are lined up which suggests in easy one quantity ought to be written above the opposite quantity. Draw a line beneath the underside quantity.

(ii) Subtract the digits within the ones place. Subtract (6
– 2 = 4). Place 4 within the ones column as proven.

(iii) Subtract the digits within the tens’ place. Subtract (8 –
5 = 3). Place 3 within the tens column as proven.

(iv) The distinction of 86 – 52 is 34

3. Subtract 42 from 78

Resolution:

 (i) Given numbers are written in column type. The larger quantity is written first, then the smaller quantity is written. (ii) First, the digits of 1’s place are taken. 2 is subtracted from 8.  8 ones – 2 ones = 6 ones. This 6 is written in a single’s column.              (iii) Now digits of tens place are written 4 is subtracted from 7.     7 tens – 4 tens = 3 tens. This 3 is written in tens column.

Therefore, 78 – 42 = 36

Allow us to discover ways to subtract 2-digit numbers utilizing an abacus.

4. Subtract 26 from 49.

Step I: Have a look at those rod.

9 – 6 = 3

 Step II: Have a look at the tens rod. Take away 2 beads. 4 – 2 = 2 We get the quantity 23. Thus, 49 – 26 = 23

5. Subtract 31 from 73.

Step I: Have a look at those rod.

3 – 1 = 2

 Step II: Have a look at the tens rod. Take away 3 beads. 7 – 3 = 4 We get the quantity 42. Thus, 73 – 31 = 42

Be aware:
To do subtraction utilizing an abacus, first subtract the beads o those rod and
then subtract the beads on the tens rod.

Subtraction with out Borrowing:

5. Allow us to subtract 7 from 29.

Step I: Prepare the 2 numbers beneath tens and ones.

Step II: First subtract those.

Step III: Subtract the tens.

Thus, 29 – 7 = 22

2. Subtract 23 from 38.

Step I: Prepare the 2 numbers beneath tens and ones.

Step II: First subtract those.

Step III: Subtract the tens.

Thus, 38 – 23 = 15

In subtraction there
are three numbers as:

95     the quantity from which smaller quantity
is subtracted is named minuend

– 23      the quantity to be subtracted is named
the subtrahend.

72       the
quantity which is the subtracted end result is named the distinction.

Right here, in subtracting 2-digit numbers we get 95 is
minuend, 23 is subtrahend and 72 is distinction.

Minuend is all the time larger than subtrahend.
