Use partial sums to find the sum of 47 and 29.

The correct answer is: 76

To find partial sums add the digits in tens place and ones place seperately.
Partial sum of 47 + 29
Step 1 : Add digits in tens and ones place seperately:
40                                    07
+ 20                   and        + 09

_____                             ______
60                                        16
