# CLASS-2LINEAR ADDITION WITH REGROUPING

LINEAR ADDITION WITH REGROUPING OF NUMBERS

Q.1)  18 + 24 = ?

Ans.)  18 =  1 Ten + 8 Ones.

24 =  2 Tens + 4 Ones.

Add Ones =  8 Ones + 4 Ones = 12 Ones.

Add Tens =  1 Ten + 2 Tens = 3 Tens.

In above equations, we have found that 12 Ones and 3 Tens. We can find 12 Ones = 1 Ten 2 Ones. Now we add obtained 1 Ten with 3 Tens and we find 1 Ten + 3 Tens = 4 Tens.

So, the number is  4 Tens + 2 Ones = 42

18 + 24 = 42        (Ans.)

Q.2)  32 + 48 = ?

Ans.)  32 =  3 Tens + 2 Ones.

48 =  4 Tens + 8 Ones.

Add Ones = 2 Ones + 8 Ones = 10 Ones.

Add Tens =  3 Tens + 4 Tens = 7 Tens.

In above equations, we have found that 10 Ones and 7 Tens. We can find 10 Ones = 1 Ten 0 One. Now we add obtained 1 Ten with 7 Tens and we find 1 Ten + 7 Tens = 8 Tens.

So, the number is  8 Tens + 0 One = 80

32 + 48 = 80       (Ans.)

Q.3)   27 + 49 = ?

Ans.)  27 =  2 Tens + 7 Ones.

49 =  4 Tens + 9 Ones.

Add Ones = 7 Ones + 9 Ones = 16 Ones.

Add Tens =  2 Tens + 4 Tens = 6 Tens.

In above equations, we have found that 16 Ones and 6 Tens. We can find 16 Ones = 1 Ten 6 Ones. Now we add obtained 1 Ten with 6 Tens and we find 1 Ten + 6 Tens = 7 Tens.

So, the number is 7 Tens + 6 Ones = 76

27 + 49 = 76        (Ans.)

Q.4)   57 + 45 = ?

Ans.)   57 =  5 Tens + 7 Ones.

45 =  4 Tens + 5 Ones.

Add Ones = 7 Ones + 5 Ones = 12 Ones.

Add Tens =  5 Tens + 4 Tens = 9 Tens.

In above equations, we have found that 12 Ones and 9 Tens. We can find 12 Ones = 1 Ten 2 Ones. Now we add obtained 1 Ten with 9 Tens and we find 1 Ten + 9 Tens = 10 Tens.

So, the number is  10 Tens + 2 Ones = 102

57 + 45 = 102        (Ans.)

Q.5)   65 + 28 = ?

Ans.)  65 =  6 Tens + 5 Ones.

28 =  2 Tens + 8 Ones.

Add Ones = 5 Ones + 8 Ones = 13 Ones.

Add Tens = 6 Tens + 2 Tens = 8 Tens.

In above equations, we have found that 13 Ones and 8 Tens. We can find 13 Ones = 1 Ten 3 Ones. Now we add obtained 1 Ten with 8 Tens and we find 1 Ten + 8 Tens = 9 Tens.

So, the number is  9 Tens + 3 Ones = 93

65 + 28 = 93          (Ans.)
