How to add three numbers of 2-digit with carry-over?
The examples will help us to learn to add three or more numbers of 2-digit with carrying.
1. Add 46, 49 and 26
Solution:
46 = 4 tens + 6 ones
+ 49 = + 4 tens + 9 ones
+ 26 = + 2 tens + 6 ones
= 10 tens + 21 ones
= 10 tens + 2 tens + 1 one
= 12 tens + 1 one
= 121
(i) Numbers are expressed in expanded form
(ii) Digits expressing ones are added i.e., 6 + 9 + 6 = 21 ones = 2 tens + 1 one
(iii) Digits expressing tens are added i.e., 4 + 4 + 2 = 10 tens
(iv) 10 tens + 2 tens + 1 one
= 12 tens + 1 one
= 121
2. Add 57, 35 and 42
Solution:
57 = 50 + 7
+ 35 = + 30 + 5
+ 42 = + 40 + 2
= 120 + 14
= 120 ← 10 + 4
= 130 + 4
= 134
(i) Digits of one’s place are added i.e., 7 + 5 + 2 = 14 ones = 1 ten 4 ones
(ii) 1 ten are carried over to tens side
(iii) Digits of ten’s place are added i.e., 5 + 3 + 4 = 12 tens
(iv) 12 tens + 1 ten = 13 tens
(v) 13 tens + 4 ones = 130 + 4 = 134
