When adding two integers that have the same sign, the process involves adding their absolute values and then attaching the common sign to the result. This can be clarified by considering the rules of integer addition:

- If both integers are positive, their sum will be positive, as you're essentially increasing the total.

- If both integers are negative, their sum will also be negative, as you're reducing the total further into negative values.

For example, if you were to add 3 and 5, both being positive, you would get 8, indicating a positive result. Conversely, if you added -3 and -5, the addition of their absolute values (3 and 5) gives 8, and you would assign the negative sign, resulting in -8. This method of addition captures the essence of the integer addition rules for same-sign integers clearly, making the process straightforward: add the absolute values and keep the common sign.
