How to Regroup in Math Addition

When adding numbers like 64 + 43, regrouping can help simplify the process and make it easier to calculate the sum. In this case, regrouping involves breaking down the numbers into smaller components that are easier to add together.

To regroup, you start by looking at the rightmost digits. In this case, you have 4 + 3. These two numbers can be easily added together without regrouping, resulting in 7. Next, you move to the tens place.

In 64 + 43, you regroup the 64 into 60 + 4 and the 43 into 40 + 3. By doing this, you can add the tens place together separately. 60 + 40 equals 100. Now, you add the ones place, which is 4 + 3, resulting in 7. Finally, add together 100 + 7 to get the total sum, which is 107.

This method of regrouping allows you to organize numbers in a way that makes addition more efficient and manageable. It's a fundamental skill in math that is essential for tackling more complex problems involving multi-digit numbers.
