Adding Two Two-Digit Numbers Using Regrouping

To add two two-digit numbers using regrouping, you can follow these steps:

1. Add the ones place digits. 2. If the sum of the ones place digits is 10 or more, regroup by carrying over the extra tens to the tens place. 3. Add the tens place digits, including any carried-over tens.

Let's apply these steps to the given examples.

Example 1: 7 + 6

When adding 7 and 6:

1. Add the ones place digits: 7 + 6 = 13. 2. Since the sum is 13, which is 10 or more, we regroup by carrying over the extra tens to the tens place. 3. The sum is 13, so the answer is 13.

Therefore, 7 + 6 = 13.

Example 2: 2 + 3

When adding 2 and 3:

1. Add the ones place digits: 2 + 3 = 5. 2. Since the sum is less than 10, there is no need to regroup. 3. The sum is 5, so the answer is 5.

Therefore, 2 + 3 = 5.

In both examples, the process of adding two two-digit numbers involves adding the ones place digits and potentially regrouping when the sum is 10 or more.
