The sum of the ones' place digits is less than ten so the answer is 119
Add 94 and 67.
First add the two ones' place digits (4 + 7 = 11).
Next add the two tens' place digits (9 + 6 = 15).
The sum of the ones' place digits is a two-digit number so
decrease the ones' place sum by 10 (11 - 10 = 1)
increase the tens' place sum by 1 (15 + 1 = 16)
Combine the tens' and ones' place sums to give the answer of 161
Another method to mentally add two two-digit numbers may be easier in some
situations.
Add 84 and 35.
First add the two tens' place digits (8 + 3 = 11).
Next add the two ones' place digits (4 + 5 = 9).
The sum of the ones' place digits is less than ten so the answer is 119.
Add 94 and 67.
First add the two tens' place digits (9 + 6 = 15).
Next add the two ones' place digits (4 + 7 = 11).
The sum of the ones' place digits is more than nine so:
Decrease the ones' place sum by 10 (11 - 10 = 1.)
Increase the tens' place sum by 1 (15 + 1 = 16).
Combine the tens' and ones' place sums to give the answer of 161
