- 43
- 53
- 63
- 73
Hint:
To find partial sums add the digits in tens place and ones place seperately.
Place value is the value of each digit in a number. For example, the 5 in 350 represents 5 tens, or 50; however, the 5 in 5,006 represents 5 thousands, or 5,000. It is important that children understand that whilst a digit can be the same, its value depends on where it is in the number.
The correct answer is: 53
To find partial sums add the digits in tens place and ones place seperately.
Partial sum of 15 + 38
Step 1 : Add digits in tens and ones place seperately:
10 05
+ 30 and + 08
_____ ______
