Right here we’ll study including 2-digit numbers with regrouping
and begin working with simple numbers to get acquainted with the addition of two
numbers.

Regrouping Tens and
Ones:

Allow us to take the
following instance:

Sam has collected 24
leaves and Jane has 7 leaves. What number of leaves they’ve in all?

Methods to add two two-digit numbers with carrying?

Allow us to observe the steps and begin studying including 2-digit
numbers with regrouping with the assistance of those examples.

1. 45 + 37

(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 underneath the underside quantity.

(ii) Add those
place digits. Add (5 + 7 = 12). Place 2 within the ones column and place 1 above
the tens column as proven.

(iii) Then add
the tens’ place digits. Add (4 + 3 + 1 = 8) and place 8 within the tens column as
proven.

(iv) The reply of the sum 45 + 37 is 82.

Technique II: 45 + 37

Add those place:

5 ones + 7 ones = 12 ones

Regroup 12 ones

12 ones = 10 ones + 2 ones

= 1 ten + 2 ones

Place 2 within the ones reply column
and place 1 within the tens carry-up column.

Add
the tens place:

4 tens +3 tens + 1 tens = 8 tens

Place
8 within the tens reply column.

So, including 45 + 37 = 82.

2. 58 + 39

(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 underneath the underside quantity.

(ii) Add those place digits. Add (8 + 7 = 17). Place 7 within the ones column and place 1 above the tens column as proven.

(iii) Then add
the tens’ place digits. Add (5 + 3 + 1 = 9) and place 9 within the tens column as
proven.

(iv) The reply of the sum 58 + 39 is 97.

Technique II: 58 + 39

Add those place:

8 ones + 9 ones = 17 ones

Regroup 17 ones

17 ones = 10 ones + 7 ones

= 1 ten + 7 ones

Place 7 within the ones reply
column and place 1 within the tens carry-up column.

Add
the tens place:

5 tens +3 tens + 1 tens = 9 tens

Place
9 within the tens reply column.

So, including 58 + 39 = 97.

Regrouping Tens to Tons of:

When the sum of digits within the tens place is greater than 9, then we regroup the quantity in tens and tons of.

3. Allow us to add 93 and 21

10 tens is 100

4. Allow us to add 49 and 64. Add those and regroup 9 ones + 4 ones = 13 ones. 13 ones = 1 ten and three ones Write 3 in ones place and carry over 1 ten to the tens column. Add the tens 1 + 4 + 6 = 11 tens 11 tens = 1 hundred and 1 ten Write 1 ten at tens place and carry over 1 hundred to tons of column.

5. Allow us to add 28, 34 and 50. Add those and regroup 8 ones + 4 ones + 0 ones = 12 ones. 12 ones = 1 ten and a couple of ones Write 2 in ones place and carry over 1 ten to the tens column. Add the tens 1 + 2 + 3 + 5 = 11 tens 11 tens = 1 hundred and 1 ten Write 1 ten at tens place and carry over 1 hundred to tons of column.
