Rule for Adding Two-Digit Numbers

To add two-digit numbers, follow these steps:

1. Align the Numbers: Write the two numbers one below the other, aligning the digits based on their place value. For example, to add 24 and 58, write them as:

     24
   + 58
   

2. Add the Ones: Add the digits in the ones place (the rightmost digit) together. In this case, 4 + 8 = 12. Write down the 2 and carry over the 1 to the tens place.

3. Add the Tens: Add the digits in the tens place (the leftmost digit) together, including the carried-over digit. In this case, 2 + 5 (from the carried-over 1) = 7.

4. Write the Answer: Write the final sum of the two numbers. In this case, the sum of 24 and 58 is 82.

This process can be summarized as follows:

     24
   + 58
   -----
     82
   

This method can be used to add any two-digit numbers together.
