Adding 2 and 3 digit Numbers Without Regrouping
Concept
The addition is a process of adding two or more items together. In math, addition is the method of calculating the total of two or more numbers to know the sum of the numbers. It is a primary arithmetic operation.
The addition that involves the sum of digits less than or equals to 9 at each place value is called addition without regrouping.
Rules
1. Place the addends one on top of the other so that the place values fall in the same columns.
2. Add each column together separately, starting with the one’s place.
3. The sums go below each column, underneath the line.
Example
Add.
526 + 352
Solution
1. Place the addends one on top of the other so that the place values fall in the same columns.
2. Add each column together separately, starting with the one’s place. The sums go below each column, underneath the line.
