30 + 5 = 35 20 + 7 = 27 50 + 4 = 54 40 + 8 = 48 90 + 5 = 95
Expand and add :
27 + 42 = (2 tens and 7 ones) + (4 tens and 2 ones) = 6 tens + 9 ones = 69
44 + 33 = (4 tens and 4 ones) + (3 tens and 3 ones) = 7 tens + 7 ones = 77
42 + 16 = (4 tens and 2 ones) + (1 ten and 6 ones) = 5 tens + 8 ones = 58
73 + 4 = (7 tens and 3 ones) + (0 ten and 4 one) = 7 tens + 7 ones = 77
48 + 21 = (4 tens and 8 ones) + (2 tens and 1 one) = 6 tens + 9 ones = 69
46 + 52 = (4 tens and 6 ones) + (5 tens and 2 ones) = 9 tens + 8 ones = 98
34 + 45 = (3 tens and 4 ones) + (4 tens and 5 ones) = 7 tens + 9 ones = 79
67 + 12 = (6 tens and 7 ones) + (1 ten and 2 ones) = 7 tens + 9 ones = 79
35 + 53 = (3 tens and 5 ones) + (5 tens and 3 ones) = 8 tens + 8 ones = 88
14 + 52 = (1 ten and 4 ones) + (5 tens and 2 ones) = 6 tens + 6 ones = 66

(6)
 51 + 10 = (5 tens and 1 ones) + (1 tens and 0 one) = 6 tens + 1 ones = 61
70 + 20 = (7 tens and 0 ones) + (2 tens and 0 one) = 9 tens + 0 one = 90
Addition with Regrouping
Let us add 45 and 23.
5 ones + 8 = 13 ones. We regroup 13 ones as 1 ten and 3 ones.
The 3 is written in one’s place in the answer. The 1 ten is written in tens’s column.
The 1 ten is written in ten’s column. Now, we add tens. 4 ten + 2 tens + 1 tens = 7.
We write 7 tens under the column of tens. Thus, the final answer is 73.
